Extra Fields not assigning to Categories

Hi,

Joomla V 3.4.8
K2 V 2.6.9
MEFG V 1.0.39

We are currently running with the versions above and with the latest K2 version, and the extra fields option no longer works on the site. The extra field groups are assigned in the category settings correctly, but now when editing an item in the admin panel, in the Extra Fields tab, it says "Notice: Please select a category first to retrieve its related "Extra Fields"...", even though they are already assigned.

Have there been any other reports of this and how do we resolve it.

Thank you.

Welcome Glen, how are you?

In such cases it is good to check for javascript errors at first, because it causes the plugin to stop working.

If you want me to check it online, just send the access information to my email.

Thank you. I just sent it to sales@.

Dear Mohamed,

I do have the same problem using k2 2.6.9 , J! 3.4.8 and JA Social ii

I didn't detect any script erros. k2 item only show the extra field category assigned in the top of the category but not those assigned in bottom.

your assistance is much apprechiated, Peer

Dear Peer,

You are welcome.
Do you have any other K2 plugins installed?

Yes JA K2 Filter and JA K2 Maps

Well, there is an issue with JA K2 Filter, I think it is a new issue as many clients have noticed it recently, please try this fix:

Edit the file plugins/k2/jak2filter/jak2filter.php

find the below code snippet, at line ~273:
replace it with this line:

Dear Mohamed ,

thanks for the hint. It is due to JA K2 Filter . If I disable the plugin it works fine.
Ich changed the line 291 within but it doesn't take effect.

Did you solve this issue for another client?

Dear Peer,

Is it possible to give me access to check it myself?

If yes, send it via the Contact Us page

credentials are in your inbox.

let me know if you need ftp access

thx Peer
