Upgrading the topcoll plugin from 188.8.131.52 to version 184.108.40.206:
A lot of our existing courses have more than the standard amount of sections (10) e.g. 18 .
After upgrading topcoll from Version 220.127.116.11 to 18.104.22.168 only this standard amount of sections is shown at the courses.
Switching moodle to editing mode, all sections are visible for teachers and admins now, but the header shows "orphaned".
Switching the setting "numsections" to the original value (e.g. 18), resp. to the real number of existing sections, all the content is accessible and shown at the course area again.
DB: We noticed that the courses 'numsections' from 'mdl_course_format_options" was lower than the max 'section' from 'mdl_course_sections'.
We could remedy the problem by switching back to the old version. However this is not a solution in the long therm.
