Click on the little blue arrow on the right side to open global content type configuration and set Parent to - None -. This shoudlset parent id to "" and save ok.

This one right? It was set to none when i saved and get the error. I tried to change it and save it and its still show up the error

Any suggestion? I can make new articles but i cant change anything in seblod, even changing field's label will show up the error

Try installing latest version of Seblod again, could be something in the database did not get upgraded properly

Hello

i've tried upgrading both joomla and seblod, still doesnt work

Joomla is 3.6.5

Seblod is the latest one [just downloaded it from your website]

Any other suggestion?

As I said, try updating seblod again.

Just to clarify, to update the seblod, all i need to do is download current seblod and use extension > manage > upload package file and upload it right?

Or there is other way that i miss?

Just wanted to make sure, thank you

Yes, just install latest package again - on installation upgrade sql is run to update database, but sometimes this fails for unknown reason, this is why repeated installation might solve it.

Hello

I have tried reinstalling seblod over and over again, it doesnt solve it

Also i noticed that if i change the parent value and save, it will show the error but the parent changes are still saved

however if i change seblod's value such as label and variation, it will show the error and will not save the changes

any idea what's causing it?

Thanks

Try if this happens if you turn off smart search, some users reported problems with it.

Hello, it was set to none before. The smart search field does save [even if the error shows up]

I have checked the smart search plugin is disabled and smart search is set to none, it's still doesnt work

Any other suggestion?

Errors seem to be related to broken joomla assets table and users recommend the following

1. Click 'rebuild' in menu manager
2. Click 'rebuild' in categories
3. Open Categories (top categories first, then sub-categories) and save them

As this happens on Seblod content types I would say open all content types and resave them too (if it works..)

Otherewise Joomal ACL manager has an option to rebuild assets table, but I can't guarantee it will work for you.

I also had this problem for many hours but trying to:

- Clear ACL app folders

worked in my case.

"Clear ACL" button in APP FOlder manager heped me too. Thanks!
