Hello,

I have K2 version 2.9.0 installed on a website. If I try to add a new item in a category view page and then add an attachment to it, the attachment button fails to open a file dialogue. Another thing that looks odd, is the way the various image, media, attachment options are displayed. I remember them being displayed in tabs, however now they are displayed in an unformulated list. Please see the attached screenshot. I hope this may offer a clue. In the screenshot, "Anexos" stands for attachments.

I am able to open a file dialogue for the image option, also embed youtube videos.

Hope someone can help!

Thanks,

Thanks a lot Fotis. I checked the template and it did have a "Optimize JS" option selected. I have deselected this but the problem continues. I'm looking through the plugins at the moment. When I click on a "Add a new item in this category" button, I get an error and one additional message in the console tab:

Error parsing header X-XSS-Protection: 1; mode=block, 1; mode=block: expected semicolon at character position 13. The default protections will be applied.
jquery-migrate.min.js?84f742cf40c3f88d54f26136e23ee75a:2 JQMIGRATE: Migrate is installed, version 1.4.1

All the best,

When I mentioned the Optimize JS option, that was in Extensions->Templates->Styles
When I go to Extensions->Templates->Templates and open the template in question, there is a directory permissions error:

"Error
The template folder is not writable. Some features may not work."

Perhaps this is causing the problem. I can't change the permissions for the folder directly. What should the permissions be exactly?

Thanks,

Actually the permission problem is unrelated. I checked on my local installation of the website and it has no such issues. It does however have the same problem of not being able to add attachments. There are no errors given in the local installation when I add a new item. Making it hard to identify the problem...

Thank you very much Fotis, that seems to be it! You meant to delete the itemform.php file itself, correct? I renamed it and the problem is solved.
