I have been experiencing a 403 error when passing parameters in the URL of a WordPress website. Has anyone else experienced this and have a solution?
The url being passed is {{website_url}}/contact-us?enquiry_type=1
However, when removing the parameter, I dont get the 403 error.
Your input would be much appreciated.
This error is generated by the Cerber Security Plugin. You can add an exception on ‘Antispam’ under the WP Cerber menu, ‘Adjust Antispam engine’, ‘Query whitelist’. You probably want
{\/contact-us\?enquiry_type=\d+}
for a regular expression to match any numeric enquiry_type value. The relevant documentation is here: Configuring exceptions for the antispam engine.
