Solved Can't upload attached images anymore

It is visible (as you can see for yourself as well when logging out ). But apart from a small problem with your mainmenu-item not being an alias I don't see any problems.

Thanks for your reply. Do you have any suggestions on how this issue can be fixed?

Where can I download Kunena two versions earlier, where there was no issue in my website?

Thanks,

Andy

You can't downgrade Kunena, so that is no option. And I can't believe this issue is the result of a Kunena update. There must be something else on your site that is causing this. 
Have you tried enabling Kunena debug and/or Jooma debug and/or Joomla error reporting?
Have you installed other extensions recently?

I have run Kunena and Joomla debugs and no bugs were found.

I am now running Joomla 5.4.0 and Kunena 6.4.7

I looked inside the Attachments sub-directories and found the recently uploaded 'faulty' image files still have the original file name, such as IMG_2194.jpg and a pixel density of only 96 pixels/inch, and they are of reduced image and file size. The correctly working images with names like f3ef32c5ca9eded833ab7449cf53fce0 are 300 pixels/inch and full size, so appear to be physically the same as the original images I uploaded.

It looks like there is a problem with the image processing. Does this information suggest a solution.

Thanks,

Andy
 

Only thing this shows is that your configuration has been changed. I.e. you've disabled Protect Attachments and maybe changed more settings. This explains the difference in filenames.

Thank you so much, I have enabled Protect Attachments again and confirm the file names issue is resolved. 

I have checked all the config settings against the manual and everything is OK.

Can you think of anything else that would substitute a low quality small image instead of a normal high quality larger image?

This is the original 0F8A3464.jpg image in my computer. 1.4MB 4480 x 3693 px 240 pixels/inch
 



This is the uploaded faulty a87f313a3ecc7c773e5ab66f35c0d24c image 69KB 910 x 750 px 96 pixels/inch
