Hi, I was trying to upgrade from Version 1.10 to 1.14 and ended up with data corruption. Apparently, there is something wrong with my /includes/media files:
*Warning*: imagesx(): supplied argument is not a valid Image resource in * /home/aseanped/dummipedia.org/includes/media/Bitmap.php* on line *210
*Error is visible on Firefox at Dummipedia.orghttp://dummipedia.org/Free_Simplified_Online_Encyclopediabut returns empty pages in Internet Explorer. **I tried to restore the database but apparently, the same errors still remain. How can I resolve this problem. (Fortunately, in shifting the website, I still maintain my website with my old webhost so all is not lost.) I have always have a fear of upgrading as I haven't done it before and haven't been able to do it. Just couldn't understand the manual, LOL.
The database is not corrupted. The error you gave indicates that you have uploaded a corrupt or missing image file, which is causing GD to fail to load the image from disk into memory. You may have forgotten to copy your image files across from your old webhost. You need to copy the whole images directory.
It's possible to see this when you do an apparently unrelated change in server configuration, because if you were previously using ImageMagick, that may have worked just fine, but now it can't find the ImageMagick "convert" utility and so is using GD, which is giving this error.
At the heart, the issue is a bug. It is an insufficiently informative error message.
Note that Michael Daly and Scheelocke are completely wrong and following their suggestions won't do any good.
