How to prevent certain words from triggering "403 Forbidden" error?

[cardboa7]

I get the following message when posting certain words to a .php page (sent from /thoughtbook.html page):

Forbidden
You don't have permission to access /ThoughtpadFileWrite.php on this server.

Additionally, a 403 Forbidden error was encountered while trying to use an ErrorDocument to handle the request.




For example, if the word "poker" exists in the request, then this error will always be triggered. E.g.: "He has a good poker face" will be blocked.

Can this issue be fixed? I understand that this is some security measure, but a blacklist is not suitable for my webpage. This page is a basic webpage that will display song lyrics.

TIA.

@Livewire I would very much appreciate your help. If you could modify mod_security to fix this (or disable SecFilterEngine/SecFilterScanPOST entirely), I'll be elated. Thank you.

Unfortunately it was recently brought to my attention that we aren't able to update/change the mod_security logs on free hosting anymore; such changes are possible on premium, however unfortunately we won't be able to make the needed changes on free hosting.
