The website digitalsplendid.agency showing 403 error. I have renamed plugin and themes directory but that did not help.

The issue is resolved by turning Web application firewall mode off.

Turning off the Web application firewall is one option.

The other option is disabling the rule that causes the 403 error:

@DigitalSplendid

It is NOT recommended to turn off the Web Application Firewall.

As an alternative, one could use the (less restrictive) ruleset from Comodo.

As another alternative, one could tweak the OWASP rules - not the rules themselves, but add some exclusions, as @Maarten. pointed out.

However, in some cases, OWASP CRS has exclusion sets for specific programs - for instance, there is an exclusion set for WordPress.

I would suggest that you start with Comodo ruleset, keep track of the modsec_audit.log file and - if necessary - activate the more strict OWASP ruleset.

Kind regards....
