not being able to make changes and save due to Wordfence

Hi,

my client is having problems making changes and saving pages. The site uses the Divi theme. I disabled all plugins one after the other and realized it is the Wordfence plugin that is causing the issues. So, the problems persist even if Wordfence is the only enabled plugin. Once I switch Wordfence off the problem goes away.

Here is the error message we are getting when trying to save a page:
An error has occurred while saving your page. Various problems can cause a save to fail, such as a lack of server resources, firewall blockages, plugin conflicts or server misconfiguration. You can try saving again by clicking Try Again, or you can download a backup of your unsaved page by clicking Download Backup. Backups can be restored using the portability system while next editing your page.

Contacting your host and asking them to increase the following PHP variables may help: memory_limit, max_execution_time, upload_max_filesize, post_max_size, max_input_time, max_input_vars. In addition, auditing your firewall error log (such as ModSecurity) may reveal false positives that are preventing saves from completing.

Lastly, it is recommended that you temporarily disable all WordPress plugins and browser extensions and try to save again to determine if something is causing a conflict.”

I already contacted my client’s host GoDaddy. They told me they had made the required Php changes.
