Seems you have deep issue with PHP maybe not only.
Today I found another bug on PHP 7.2 mcrypt is missing so I need to install and reconfigure PHP 7.1 again but problems do not stops here.
Installed PHP 7.1
Configured PHP 7.1
Unistalled PHP 7.2
Apache stop to run, all website down.Once again I see an old bugs error: No space left on device AH0023: couldn't create mpm-accept mutex
In all this time you do not resolved this PHP issue that made everything broken.
You are a good team but please fix all this PHP bugs. It's not possible that only to install or uninstall PHP let's Webuzo goes in total TILT. I need reboot the server for see all service work again as service Webuzo restart doesn't help.
So you create issue with the new PHP 7.2 because there are bugs but in addition to this if I work to resume the previous PHP I see others bugs that by uninstalling one of the two PHP made everything broken.
All time this issue occurs I have downtime. This downtime is not because I have hosting provider issue but because it's Webuzo!
Also I reported sometime PHP mail stop to work, I really hope you will not keep this bug as this issue about uninstalling some PHP that I continue to report but continue to see is not resolved.
