Hi!

I have Community Surveys 5.7.0, Polls 5.2.1 and CjLib 3.2.4 installed (should be the latest versions right now). My system is on PHP 7.4 (again, after the recent trouble with CjLib).

When I try to uninstall the Surveys Package (only the package), the installer throws the message

"Warning
Trying to uninstall unknown extension from package. This extension may have already been removed earlier."

At this stage the site still works but the Survey component is still there.

When I then try to uninstall the component, it totally crashes the site (Error 500), similar to what happend with the upgrade to CjLib that required PHP 8. I tried the same procedure under PHP 8 but the behaviour is the same.

I can "fix" it by reinstalling Community Surveys.

Thanks!

Frank

P.S. Why uninstall? I need the functionality that users can change their answers after submitting the survey.

EDIT:

When I try to install CjLib v. 3.2.4 from git (the zip-file), I get a warning as well:
"Warning Rename failed."
Uninstall of the cjlib package does also crash the site and throws error "500 Library path /libraries/cjlib cannot be found.", followed by "Warning Trying to uninstall unknown extension from package. This extension may have already been removed earlier." when going back to the control panel.

At that point /libraries/cjlib has been deleted on the server. I cannot access the extension manager anymore, it will give the error "500 Library path /libraries/cjlib cannot be found. " until I reinstall CjLib
