Check your File table and make sure there are no records with null ClassName fields.

There are 4 images in there with blank ClassName fields, all from the assets/image-gallery/album folder that I couldn't delete ...
Should I delete these from the database?

Hi everybody.........!

Im using version SS 2.4.4

First Case :

Im also getting the same error. When i create a new image gallery page and click the go button, the gallery page doesn't appear in the site tree as the normal page types appear within a flash of second.
So what i do is, i'll refresh the the page once, then the gallery page appears in the site tree.

Second Case :

Any how the page is created after the page is refreshed, but here is the second error, When i save the page, it says ' Error Saving '.
This error is thrown for some time. and then n then when i change the page name by luck the gallery page gets saved.

Please Uncle Cheese ............ what is this, why is this problem occurring? and what is the sollution.
Any body with the answer, please help me out, i'll be thank full to u.

I fixed the problem I was having by deleting the images with the blank class names from the database.

I've since had the problem again with another website and something similar with another website again. It seems that sometimes when you create a gallery page, it creates multiple 'Gallery' folders within the 'Files and Images' section of the CMS (for example, on one website I built, after creating a gallery page and then getting the error when trying to save, I looked at the Files and Images section and found that it had created one folder gallery 'Gallery' which was empty, and one folder called 'Image-Gallery' which contained 2 folders also called 'Gallery', one of which contained a folder called 'Default album')
I fixed the problem by deleting these folders from the Files and Images Section, then going back to the Gallery page and clicking Save again.
It seems that the image gallery gets confused when there are multiple folders called Gallery and so returns an error. As for why it's creating multiple folders in the first place? I have no idea.

I'm now getting a different but similar problem occuring where when creating albums it's sometimes creating duplicate album folders in the files and images section (these duplicate folders are appearing both inside the 'image-gallery' folder and outside it), and if I try to upload images to that album they're coming up blank. If I try to visit that album page on the website it tells me the page doesn't exist. I was hoping to fix this problem in the same way as I fixed the gallery problem, deleted the duplicate folders from the files and images section, and saved the album again, which created just one album folder this time, but it was outside of the 'image-gallery' folder, and the website is still telling me the page doesn't exist. Tried to delete the affected album from the albums list but nothing happened when I clicked delete. Am now trying to find some sort of error message.

I was getting the same error. I changed the page name, nav name and title then I was able to save and it changed the names under folders/files.

Then I created a gallery and added one image but the thumbnail is blank and the image doesn't show:

I know I've comes across this before but I just cannot for the life of me remember what I did to fix it. Any ideas anyone?

Got it, just edited the .htaccess file in the assets directory and it solved it.
