Internal server error (500) when activating the monthly quota plugin

[volker]

Hello,

just a short notice, if anyone else has this issue: when activating the monthly quota plugin the timetracker stopped working.
Login attempts led to a HTTP 500 error. Logins to other groups that didn't have the plugin activated still worked.

A quick remedy is to remove the plugin from the list of enabled plugins directly in the tt_groups table in the database:

Code: Select all

update tt_groups set plugins="ch,mq" where id=1;

For the id please enter the correct one from your tt_groups table.

My Timetracker version is 1.18.37.4748.

Cheers,
Volker

What exactly does your web server error log show when error 500 occurs? Copy and paste the error log fragment here to see if we can help to identify the issue.

It's a docker installation with logs linked to stdout/stderr. php.ini is set to production settings so there was not very much information. I'll try to reproduce the problem with usefull logging in action. PHP is a 7.3.0.

Error 500 is not printed in Docker console output? Am I missing something?

Just created a second image/container with error logging enabled. The interesting part of the error_log is:

Code: Select all

Indeed the function cal_days_in_month() isn't defined anywhere in the code.
Update: And the calendar extension is not installed. This seems to be the problem.

Nope. The standard PHP image has no active php.ini in /usr/local/etc/php. So "docker logs -f" also stays quiet.
I just built a custom Dockerimage with error logging enabled.

The missing calendar extension was the problem btw.

For docker users, ther was also a recent fix to replace cal_days_in_month with a generic date call, so calendar support is no longer required when using the Monthly Quotas plugin. See pull request #99 in code repo.
