Thank you. We’ll respond to you asap.

Hello,

Reinstalling the plugin should solve the problem. Please follow this guide to reinstall the plugin:

https://cleantalk.org/help/update-wordpress-security

Does it work?

Hi,

it works now temporary.

I installed the previous version of the plugin. (security-malware-firewall.2.134.3.zip)
Because a normal re?nstall did not fix the issue.

Can you investigate this further. Because upgrading doesn’t work now.

Hello @cedericvh,

Please contact us via our private Ticket System for further investigation:
