Solved Can't upload attached images anymore

Hello,

We don't advise to install Kunena 7.0 beta on production sites.
There will be a release candidate untill the translators make the update on their translations so a stable release could happens in the begining of 2026.

Thank you for the information. I will wait for version 7 next year and in the meantime carry on with Kunena 6.4.7 on my Joomla 6.0.1 site and hope that Joomla's "Behaviour - Backward Compatibility 6" plugin keeps the forum running properly in the meantime.

Question: does that sound like a reasonable decision?

Thanks,

Andy

No, that doesn't sound like a reasonable decision. The most reasonable decision is to restore a backup with Joomla 5.4 and Kunena 6.4.7. 
And please be so kind as to create a new topic everytime you have a new problem. Your latest problem doesn't have anything to do with uploading attachments, so topic title is very confusing.

Thank you for your advice, sorry about going off topic.

At last, I have discovered that Kunena is being conflicted by Joomlashack's Shack Forms Pro 5.1.33, the excellent mail form extension. It only happens when the "Upload / Show upload" setting is set to "Yes". The software in Shack Forms Pro that processes uploaded/attached images at 96 pixels/inch is unfortunately doing this for uploaded images in Kunena forum as well, which is not wanted.

I have switched off the 'Show upload' setting and am awaiting a bug fix from Joomlashack. This conflict has been happening since Joomla 5.

Thanks to everybody for your help.
