Calendars not showing in backend

Hello,

ISSUE: Calendars are not showing in 'Manage Calendars' backend.

BACKGROUND:
I installed JEvents a few weeks ago successfully with around five to six calendars being pulled from TeamUp calendars using cronjobs.

Last night I noticed one event was not pulling across from Teamup. I tried deleting the calendar and category and starting afresh, however, this is where more problems emerged. The calendars in 'Manage calendars' would sometimes be displayed in the backend and sometimes there would be no calendars.

I decided it might be best to uninstall JEvents and start from scratch. However, uninstalling is not a complete uninstall. It still remembers the past events, calendars, categories etc.

After a few attempts, I didn't get very far. I was able to delete all previous events, and whilst it was displaying the old calendars, managed to successfully delete one of them. Now, it is showing no calendars. Additionally, if I now try to create a new calendar either from scratch or imported from a .ics, the calendar is successfully create but does not show up in the backend.

It is all very strange and frustrating. Any advice would be appreciated.

Thanks.
Hello and thank you for your detailed response.

Yes, the import is using an automatic cronjob (URL).

Straight after posting this, the calendars once again returned. I took this opportunity to delete them all and remove them from trash.

I began to create new calendars again (from an .ics import) whereby I encountered another problem - at the end of the import log it said, "Sorry, we failed to automatically create the category: Live Music"

I returned to the backend and deleted all categories and started again.

I am currently up and running and back to normal (I think). Perhaps this problem may return in the future so I will update this thread if it does.

Thanks for your help.

Hi magnetar,
we are really sorry for the issues you are facing. Indeed it looks like a weird issue!!

As you point out several scenarios, let me go through them:


Last night I noticed one event was not pulling across from Teamup.


Maybe the event had the same UID identifier as any previous version. How is this import? Is this an automatic import using a cronjob and importing from URL?

I tried deleting the calendar and category and starting afresh, however, this is where more problems emerged. The calendars in 'Manage calendars' would sometimes be displayed in the backend and sometimes there would be no calendars.


That's weird, but probably related with the categories removal you did. Did you actually sent JEvents Categories to the trash and then empty the categories trash? Also, can you think of a pattern for when calendars were showing and not?

I decided it might be best to uninstall JEvents and start from scratch. However, uninstalling is not a complete uninstall. It still remembers the past events, calendars, categories etc.


Historically we have neverd performed a full uninstall as to avoid data loss when uninstalling by mistake...

So if you want a fully uninstall with data removal follow these steps:

1. Uninstall JEvents
2. Use PHPMyAdmin or similar and remove these tables from your DB:

#__jevents_catmap
#__jevents_exception
#__jevents_filtermap
#__jevents_icsfile
#__jevents_repetition
#__jevents_rrule
#__jevents_translation
#__jevents_vevdetail
#__jevents_vevent
#__jev_defaults
#__jev_users

That will fully uninstall JEvents (unless you had other JEvents Club Addons installed in which case you need to take care of them)

My advice is to perform a fully uninstall cleaning your database too and then install the component and add the calendars again. That should work with no issues.

Also if you experience again the missing event thing, please contact us and we will check into it

Best!!
