I have a error 403 when I try to change my password or upload a new module or component...
I check on your website and found this treat :
Please go to Components, Admin Tools and click on the Web Application Firewall button. In the new page, click on WAF Configuration. Find the Disable editing backend users' properties option and set it to No. Now you can create and edit all users on your site. For security reasons, remember to re-enable this option after you're done adding/editing users!
When I click on Web Application Firewall button, I have this message: Error
You are not authorised to use this feature
Please I need your help. I can't upgrade my website or change anything because of this error 403
Thanks
