Hi,
I experienced some issues with Seblod and Joomla 3.8.0:
- Yesterday I tried to update some sites that used Seblod 3.13.0 to Joomla 3.8.0. In some cases it worked, in some I got a blank screen in the backend. I had to install backups of those sites to get them running again.
- Today I updated seblod to the new 3.14.0 version and now those updates were successful.
- So I continued to update my other sites. I updated Seblod to 3.14.0, performed the update to 3.8.0 and now get an new error in one of my installations: "Error displaying the error page: Call to undefined method JAdminCssMenu::addChild(): Call to undefined method JAdminCssMenu::addChild()"
Any idea how to solve my new issue?
Many greetings
Sven
UPDATE: I'm not sure if the new issue is caused by seblod or maybe another component - I will have a closer look at it.
Hello Sven,
For the 1st one: SEBLOD 3.13 took care of the B/C issue introduced by Joomla! 3.8, but there was a slight issue on our side only when more than one SEBLOD Admin modules were published... so I guess that's why you had blank screen on some of your sites.
For the 2nd one: The slight issue for multiple SEBLOD Admin module was fixed in SEBLOD 3.14
For the 3rd one: Currently I am not sure how this could happen. Please let us know.
In any case, feel free to execute one of the 2 methods to disable the module, at the bottom of the blog post. And when you are able to access the back-end I would even suggest to uninstall the SEBLOD Admin module, and to create a (Joomla!) Admin module using the SEBLOD preset (or a custom back-end menu if needed) ... as the SEBLOD Admin module is now deprecated. With SEBLOD 3.13/SEBLOD 3.14 the purpose was (to try) to avoid broken back-end with Joomla! 3.8, but it's gonna be removed from the Core package soon.
Regards,
Saba.
Hello Saba,
thank you for your explanations and your fast support! Meanwhile I successfully updated many other sites to J3.8.0 after updating seblod to 3.14.0.
I did not figure out what caused the issue in the one installation I mentioned yet. But I will inform you when I know it.
Regard
Sven
Hello Saba,
just want to give you a short feedback. I did not figure out what caused the issue. I installed a backup, updated Seblod to 3.14.1 and the Update to Joomla 3.8.0 was successfull this time - without any problems.
Regards
Sven
Hi Sven,
Thank you for the feedback! :)

I experienced this issue today when upgrading my joomla from 3.7 to 3.8.1 and I was unable to access my joomla backend. What I did to solve this problem is deleting these folders :
/administrator/modules/mod_cck_menu
/administrator/modules/mod_cck_quickadd
/administrator/modules/mod_cck_quickicon
and then installing the seblod update.
