503 Error on trying to install on HostWinds server
Here are a few things to try:
- Remove these files from /cmsb/ .htaccess, .user.ini, and php.ini
- Test a phpinfo.php file to check php version: <?php phpinfo(); ?>
- See if you can find the error logs for your website as they would contain more information.
A 503 error is for "service unavailable" which usually indicates an overloaded server, or in this case, I'd take a guess you might have an overly sensitive firewall or security extension installed (mod_security, etc).
Hope that helps! Let me know if any of the above tips make a difference.
