[SOLVED] 403 Forbidden Access

Hoping someone can advise.

I had to move an Opencart ver 1.5.5.1 store to a new VPS server. It appears to be up and running OK from the front end.

However the problem I now have is that if I attempt any changes at the back end as admin - for example set store to maintenance mode, adjust product price etc. the change is not implemented and I get the "403 Forbidden
Access to this resource on the server is denied!" screen

Could this be a PHP issue? PHP version is currently 7.1 and I've attempted to match PHP settings per the old old server. Maybe I've missed something?

So basically I can't make any admin changes - any help appreciated!

Could be a web application firewall, such as ModSecurity. Check in you hosting control panel or ask your host to temporarily disable it.

Thanks for the response, it was useful:)
After further conversation with the VPS host it seemed to come down to a combination of ModSecurity settings and server memory limits. Some tweaking of both appears to resolved the issue.
