Randomly 403 Forbidden Access on modules after 3months. Topic is solved

[chris2k13]

Hi I'm randomly now getting error when I save a module or close.
I have not made any configuration changes for months and have creating modules frequently and now out of the blue I can no longer edit any modules?

403
Forbidden
Access to this resource on the server is denied!


This is very strange can anyone help, I have been creating some modules today so to suddenly throw up 403 error is so strange.
I found out only getting when I try to edit the Module Class, everything else is fine

This could be a mod_security problem. Hosting services use it prevent upload of form data containing dodgy content but the rules they use often produce false positives. Ask your hosting service for advice?

thank you so much!
yes mod_security problem, disabled it on cpanel and works now.
I wonder what happened, do you have any suggestions?
