How do I fix the 500 error when trying to use the page optimization tool?

Hi there,

Tawny from Moz's Help Team here. I can confirm that we are getting a 500 response from your server. Unfortunately, other than making sure you're not blocking AWS and that Rogerbot is allowed, I'm not sure what else you can do. Have you checked over your server logs with your web developer to see if you can find any additional information as to why your server responded with a 500 error when we tried to crawl your site?

If you've got any more questions, feel free to reach out to us at help@moz.com and we'll do our best to sort things out!

My experiences with a code 500 error on the Wordpress platform, have in most circumstances been caused by a memory limit issue set forth by Wordpress. Assuming your using wordpress the way you would increase your memory limit is within wp-config.php by changing the values on the memory limit to something along these lines:

define( 'WP_MEMORY_LIMIT', '256M' );

I'm pretty sure even the AWS ec2 micro has enough ram to cover 256. If it's not that, I would just run down the list of diagnostics:

Try running your site through https://technicalseo.com/seo-tools/fetch-render/ or https://redbot.org or https://www.screamingfrog.co.uk/seo-spider/  only for 500 pages

I have never seen any web application firewall make 500 errors it sounds to me like your server is underpowered or is going through some sort of code issue definitely look through your logs.

If you can't get through redbot.org call the developer

Hope this helps,

Hi Tom,

Thanks for your response, we ran our site through the links you provided and didn't have any issues. My developer is still not seeing any issues in our error logs on our side either. Any other ideas on how to fix this?

Thanks,

Can you send me your domain? PM or here if you're ok with that?

[BlueprintMarketing]

This might be a 301 please send the URL via PM?

If it's 301, perhaps you'll get lucky and the htaccess will be the cause.

[GogoBusinessAviation]

Sure our domain is https://business.gogoair.com

[BlueprintMarketing]

Thanks I will test it dis this happen on all ur or just one or two?

[GogoBusinessAviation]

This error is occurring on all our URLs

[BlueprintMarketing]

You just made the move to https right?

I ran a 301 check http 301’s to https

google shows that the site is not yet In the SERPS as https

what I think is happening is that you have to run a search & replace for all http URL’s making them https URLs in the database so the bot will not have to crawl http and do a 301 to https.

I will test useing DeepCrawl if you say ok?

Is the moz campaign setup to crawl http or https?

The site should work just fine with a search & replace

I will send you the DeepCrawl

hope Le that helps,

Tom

Hi Tom,

Yes we just moved to https. When I look at the Moz campaign it just says it's tracking the subdomain business.gogoair.com. It doesn't say whether its http or https, so I started a new campaign using https and tried using the page optimization tool and got the same error as before.

We are hosted on Azure using a Web Application Gateway, are there any specific things we need to do in moz to set this up properly?

Thanks,

Brittany

This is the best guide

Use this setup, you don't want to duplicate your web site HTTP to HTTPS if needed.

Start a new moz campaign with https as the URL
