Dec 1st
So…I came across this error on a clients site which he was receiving when trying to install a 3rd party script.
The session.save_path setting in your php configuration file (php.ini) is not set or is set to a folder which did not exist. You might need to set the save_path setting in php.ini or verify that the folder sets in save_path exist.
It’s a pretty simple fix in the servers php.ini. More >

Nov 3rd
I came across an issue for the first time where the cPanel icon was missing in the list accounts section. After digging around WHM, I found where the function was disabled.
- Log into WHM
- Select “Tweak Settings”
- Uncheck the box next to “Disable login with root or reseller password into the users’ cPanel interface. Also disable switch account dropdown in themes with switch account feature”
- Click save
After hitting save, you can go back to the list account section and the cPanel icon will be back.
