I get the following error when installing wordpress with wordpress toolkit
WP Toolkit version
Version 6.5.4-8879
and Plesk Obsidian 18.0.67
Has it happened to anyone else?
PleskExt\WpToolkit\Feature\Vulnerability\VulnerabilityFeature::setInstanceCoreVulnerabilityPolicies(): Argument #2...
I just found the problem, I had modsecurity activated with the free comodo rules, I deactivated it and the problem was solved, confirm to me if that solution works for you.
Exactly the same thing happens to me, but I discovered that it is a problem of the first blank line when you make a reply or a forwarding, if you delete it the email works even with html format, however if you reply without deleting that line you can neither save as a draft nor send the mail...
