error 403 when trying to install
Have uploaded the zip and unpacked in on the site
Then ran the cmsb/admin.php but get a 403 error
Have disabled user.ini php.ini .htaccess and still get the error.
Is there a log or somewhere to check what the issue is.
Site is running php 7.4 and folders are set to 755 and files 666
Thanks for the update - I'm glad you were able to resolve the issue!
For those who might be curious, some webservers will not open files with certain permission configurations - in particular they will prevent access to files that are too permissive. In this case, having the permissions set to 666 allows anyone to write to the file, which was likely the cause of the issue. Tightening the permissions to 644 (only the owner of the file has write access) satisfies the webserver's rules.
