If you are getting error 500 when trying to access CWP, that means that, for some reason, your CWP automatic updates don't work
Example Error message:
PHP Fatal error:
The encoded file /usr/local/cwpsrv/htdocs/resources/admin/include/cron.php has expired.
in Unknown on line 0
The solution is to manually update CWP from the bash shell.
cd /usr/local/cwpsrv/htdocs chattr -i -R /usr/local/cwpsrv/htdocs/admin wget static.cdn-cwp.com/files/cwp/el7/cwp-el7-0.9.8.1160.zip unzip -o -q cwp-el7-0.9.8.1160.zip rm -f cwp-el7-0.9.8.1160.zip cd /usr/local/cwpsrv/var/services/ wget static.cdn-cwp.com/files/cwp/el7/cwp-services.zip unzip -o -q cwp-services.zip rm -f cwp-services.zip
Don't forget to change the version from this example 0.9.8.1160 to the latest version which you can find on this link:
