Sound as error with mod_security and it's configuration.
You must check in hosting control panel (cPanel/WHM/webmin or other) http error log. There is information what's really happening in execution of this wp-login.php. Unfortunately we can't help you and you need to contact your hosting provider to resolve this.
Yes.
This happens on new and redesigned G+. But you can link them to Google Maps where reviews can be seen and written too.
You can't use ALT text to background images.
If your images are loaded as img tag then you have title, alt. Example:
But background images isn't regular images loaded with img tag. They can be loaded only with CSS styling. And therefore they doesn't comes with title and alt. Example:
As you can see you can't use title or alt for image there. Only way is to define title as this:
or better this one:
I know that isn't 100% background but also helps.
Alternative way can be ARIA. If you love background images but really wish alt text you can use WAI-ARIA and define them as:
...
But GoogleBot doesn't support aria-label for now.
Building rewrite URLs one-by-one for webserver isn't suitable for your needs. All you need is to use redirect map based on your webserver or use/create CMS redirect map.
If your URLS for redirects around 100 you can use webserver configuration typing all of them in server configuration. But when links become 1000+ then this will slow down webserver and make configuration not-so-simply for changes. This is why almost all of webservers support redirect map:
https://httpd.apache.org/docs/2.4/rewrite/rewritemap.html
https://www.nginx.com/resources/wiki/modules/lua/
http://www.iis.net/learn/extensions/url-rewrite-module/using-custom-rewrite-providers-with-url-rewrite-module
Then all you need is to build redirect map for your webserver and do one quick test in dev environment. With many redirects anything can happen - ram or cpu hogging, etc. Once you check and recheck this you should make also CMS redirections with some plugins or write new one. You should keep both (redirect map and CMS redirects) working for some time (6 months or year). Then you can drop redirect map and use only CMS redirects for old bookmarks.
TL;DR - yes and no.
Long story - you can't disavow links only with spam score. All you need is to go and check manually with human is it look spammy or doesn't. Because tools can be easy fool and make legit sites to look spammy or vice versa. That's why you can't rely only on this machine generated number.
You also can use Majestic too. All you need is to verify your domain there and do export of domains and blind disavow all domains with TF < 1 and with ref. domains < 10. But you can change all domains with TF<5 or even TF<10. This give also good list of "bad" domains.
If you have enough time then you need to use SeachConsole, OpenSiteExplorer, Ahrefs, Majestic and WebMeUp. You need to signup and get all links for your domain (both fresh and historical). Then you need to export everything in CSV. Then merge all CSVs into one huge spreadsheet only for links; remove duplicate links and then to locate bad links with human inspection. Please check this article for useful tips:

Now bad news... this is slow and expensive process. But this is only way to make almost perfect link profile for your domain.
You need definitely to check this article:
https://moz.com/blog/hreflang-behaviour-insights
https://moz.com/blog/open-source-library-tool-check-hreflang
and fix 302 with correct hreflang annotations. Also don't forget default language.
About linkbuilding. After you fix this "hreflang" then you should do both - building links for main (default) language and build links for country languages from country specific resources. Like french sites linking to french directory/pages.
TL;DR - This can be all or nothing.
You must make account in SearchConsole and verify your site. Then you must look pages one-by-one for 90 days period for keywords. If all pages are suddenly drop in one specific date - this can be hit from algo penalty. If they're drop in different times this can be some technical issue.
But this also can be due your new site. New sites often get temporary boost in SERP and then they're drop. This is caused from your linking profile and domain/site age. You need little bit patience then to get somewhere in 2x or 1x or even 0x positions in SERP. Just don't rush things with linking. Just little bit patience.
That's why - this can be all or nothing. If you're hit from algo penalty then sudden drop everywhere. If you're drop due on different dates can be some technical issue. If you're mixed can be fresh domain, but also check linking profile just to be sure.
Today Twitter make changes and implementing new button so shared will be lost.
OSE count non-www and www as different because bot need to crawl all pages to catch 301 redirect. This isn't real-time or quick so you need little patience. Please check canonical on your WordPress and change all of them to new host (www.example.com). You need to change host in WP -> Settings -> General and in Google SearchConsole preferred domain.
For social buttons - there are few ways how they get URL for sharing. Long story short - with site move you will lost all of your sharing statistics except G+ pluses. There is no way to recover them except if you use data-url for them. But you will share different URL then.
IF you wish to keep number of social shares then you need to 301 www to non-www. Within time OSE will catch this 301 and links will push DA higher there.
Anyway - look messy answer but i know this situation. When you make site one of first job is to check www and non-www also http and https. This make 4 checks (and few more with strange domains as ftp.example.com; mail.example.com) totally just to be sure that site can be seen only in one host. Because later 301 can broke something. And delaying this 301 make things more and more complicated.
This is tricky question and i will give shot with mine own testings:
But this is with mine own testing where links are visible, counted in OSE. Probably 0-25 is near 75% (and over!) from whole WWW.
There isn't best solution in this case.
All you need is to prefer some http or https and to migrate everything to preferred protocol. This mean that you shoud:
In theory this is. As you can see "fix canonical" is just one small step there.
Text will be indexed but definitely will be "less-valued" than non-hidden text. So please put text to be visible to user without interaction if you wish all text to be indexed and searchable. There are many experiments in internet for this and here is link to some:
http://dejanseo.com.au/experiment-results-can-hidden-content-rank-well/
However it’s still the best and safest practice to show any important content and keywords in the visible part of the page.
There isn't one-answer-fit-all solution.
You should watch that links and sites for sure. For now keep them as-is. There are many old, authoritative and trusted directories in web. Examples can be found easy - Yellow Pages, DMOZ, Yelp, etc. So you should watch not only your links but also whole directory for spammy submissions, anchor text modifications, new links, spammy changes, etc. This can be the moment when directory will be turned into toxic asset and links can become bad. You should also watch for unusual changes - example i know software directory with links for "insurance in NY". Because site change this owner and new one start selling links with anchor.
This is why i cannot give you advise based on your question. But you should see some statistical numbers (DA/PA/Spam/Alexa/TF/CF/Ahrefs/social shares). You also need to see few pages of site and then you can know is site good and bad.
You can return same page with different content based on cookie safe. Just don't forget to add "Vary: Cookie" in headers. This will to told browsers and bots that this content is different based on cookie.
