@stewagner – Are you using any sort of custom sort order for the albums? Our next release does have a minor modification related to sorting but I do not believe it will be specifically linked to this issue.
Also, there could be a plugin conflict going on here or at least it should be ruled out. Have you tried deactivating all of your plugins, clearing your browser cache (and site caches if you are using a caching plugin), then reactivating the NextGEN plugin?
If this fixes the problem then it was likely one of the deactivated plugins that was causing an issue. Now, retrace your steps activating each plugin and re-checking to see if the problem returns. If it does then that last activated plugin was probably the one. Keep reactivating and in most cases it is also best to keep checking after each plugin, sometimes there may be more than one plugin on a site that will create an issue. If you do find one (or more) plugins causing this problem we would greatly appreciate your feedback on them so the developers may address them as soon as they can.
Also to note, in rare cases it may be the theme itself that is causing a conflict so while you have just the NextGEN plugin activated you might consider temporarily switching to one of the default WordPress Twenty series themes and see if this corrects the issue as well.
If the problem still persists after all of this we would still want to know, even more so, as we will still want to sort out the issue and may need additional details.
Thanks!

Hi Cais,
I deactivated all plugins, cleared browswer cache and activated only NextGen: Same errors!
I tried with IE instead of Firefox: Same errors!
I also switched to theme twenty sixteen: Same errors!
I googled that many other users had the same error with NextGen for mseveral years already: You still don’t have a clue why?
Brgds.

@stewagner – We’re not able to reproduce this issue ourselves so we do not know why it is happening on some sites. Please send us a Bug Report (http://nextgen-gallery.com/report-bug/ … please reference this topic) so we can get a better look under the page at your site.
Please include as many details as you can about your site and the issue at hand so we can move on this as fast as possible.
Thanks!
– Cais.
can you see it on the sample page I created for you, at least?
@stewagner – Yes, I can see the issue on your site; I’m not disputing in any way that you are experiencing a problem but as it is I cannot tell why that is the case.
– Cais.
I realized that the gallery preview images, stored in the “dynamic” subfolder, are files with extremely long names, such as “Radtour-2003-1.JPG-nggid03537-ngg0dyn-220x220x100-00f0w010c011r110f110r010t010.JPG”
Could it be that this has something to do with the problem?
It does cause a problem with some Backup Plugins (e.g. BackWPup) that fail to pack theses files in a tar archive as the filename is too long.
@stewagner – Although in some cases some back-up plugin run into trouble with long file paths I do not see this being the case with this operation here.
– Cais.
Could it be a memory limitation?
… my server’s max_execution_time is 30 and memory_limit is 96M.
Could that cause the error?
@stewagner – Have you tried raising those limits?
– Cais.
I would if I could but that would imply an expensive upgrade of our webiste packet.
Could you on the contrary reduce your limits accordingly and check if this causes the error?
– Steffen
@stewagner – The limits if they are being crossed on your site could very well be due to something very specific to your site. We have many sites that work fine with lower limits (although we do not recommend operating with limits that low).
– Cais.
I post again the complete 4 error messages as this matter is still unsolved:

I can see that lots of other users have the same problem:

… with even more users still dropping into the thread with the same error. Unfortunately, even though these errors are sometimes more then a year old, you could not offer real solution to the problem, which is sad and unacceptable.
Bbpress which is mentioned as a possible conflict plugin is installed but deactivated.
Please check the lines mentioned in the error codes and come up with some code changes that hopefully solve the problem.
@stewagner – There is no generic solution to this issue because it is not a general issue across all sites. The problem does occur on some sites, and in some cases it has been resolved and in others it has not.
We are more than happy to look at your site specifically if you would care to send us the Bug Report I suggested earlier.
Thanks!
– Cais.
