Form Generator 403 Forbidden Error

By andreasml - August 26, 2022


I am trying to create the code for a form in Form Generator, and I am getting a 403 error message (Forbidden - You don't have permission to access /logbook/admin.php on this server)

Is there anything I can do?

Hi Andreas,

A 403 error is generated by the server, so it could be due to a number of things. Some initial questions to help narrow things down:

  • Does the same error occur if you try to generate a form for a different section, or using different form generator settings?
  • Is "/logbook/admin.php" the correct location of your CMSB installation?
  • What version of CMSB, PHP, and Form Generator are you running?
  • Does the server have any security tools/programs, such as ModSecurity, suhosin, or other WAF?
  • Do you have any custom rules in your .htaccess file?

It may also be worthwhile to raise the issue with your server admin - they may be able to point to a more specific cause.

Hi Daniel

Thank you for your help. I communicated with my server company. As you said, it was a server Firewall issue (ModSecurity). They helped me to create an exception (switch off a security rule) and the issue was solved.

Kind regards,
