Sometime CyberPanel tend to throw 500 internal server error while accessing login page via port 8090, which make it difficult to access everything include websites.
This 500 Internal server error is common among CyberPanel users, it caused by either missing of configuration files which often appear when you try to upgrade its version via admin area or corrupted of some files.
Like I stated above, this error is likely caused by missing of some files when you try to upgrade it, get back login page with my tip.
While the error is prompt, make sure your sites are online and their login pages are accessible to implement my tip.
Remember, this tip will work if your server or panel is not hacked and all websites are working fine, which mostly is not easy to note if you are not accessing it.
To solve the error and get back login page on port 8090, you have to re-upgrade the CyberPanel with following codes.
sh <(curl https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh || wget -O - https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh)
OR following code for sudo
sudo su - -c "sh <(curl https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/preUpgrade.sh || wget -O - https://raw.githubusercontent.com/usmannasir/cyberpanel/stable/…Once you accomplish executed the code via terminal, then you ill get back login page of CyberPanel on port 8090, use putty program to execute one among of above codes, wait until the end to see the outcome.
