Have you removed the code I noted in that one thread?
No idea why the other thread was closed.
I changed the entries like you had advised:
So the first problem was solved - if you click on a thumbnail the according picture is displayed. But if I try to edit this picture, or if I choose it as category image this message appears. Also changes in the headline of the picture will not appear in the category (if it is the last picture).
Did you remove the line by mistake below the code noted to remove?
Content visible to verified customers only.
Looks to me like that has been removed by mistake as your orderby is empty
Try downloading 2.4.3 reupload showimage.php and lets start fresh.
I have reuploaded showimage.php today. It is still the same. The image is displayed. Image Tools -> Edit Image: Something is changed and afterwards the above mentioned message appears. The change is executed.
Same happens if you click on "Image Tools -> Printable Version". The printable version is displayed and some links appear, e.g.:
That link works so basically from what I see we are back to this. Remove this from showimage.php and the link without c=5 should work as that is what has worked for quite a few people. I would suspect the issue is because of a vbulletin hack as I am unable to get any issues on a clean vb and vbgallery install with or without the catid present.
The message is still the same, the corresponding message in English:
"The following errors occurred with your search:
Please specify some words or valid user names to search on. There were no matches for those that you specified."
I tried again to remove the code trying not to forget something or to remove too much code. The result is again an error message after changes are made and I click on "save Changes":
