Has anyone had problems with Wordpress plugins on their blog causing payment issues on the main site?

[Amelia.Coleby]

Looking to migrate a subdomain Wordpress site onto the main domain, but the payment system breaks based on one or more of the plugins used on the blog having been linked with spammy activity in the past. Need to isolate the plugin and remove before migrating or it'll break the site!

Has anyone had any similar issues with some of the following plugins?

• Akismet

• Wordfence Security

• Subscribe2

• Timber

• Backup Buddy
