Division by zero error?

I have a Maxigallery upload problem. I have a gallery which had been working and now I am suddenly getting a strange error. I promise nothing about the code itself was changed (I haven’t been on this site in some time). I just got a call from the customer this morning saying they couldn’t upload a picture.

Here is the error message I’m getting:

---

« MODx Parse Error »
MODx encountered the following error while attempting to parse the requested resource:
« PHP Parse Error »

I’ve tried uploading all types of files and I’m getting the same error on everything. I do think that my web hosting provider may have done an update on the server this weekend which could have changed the ImageMagick and/or PHP versions.

Has anyone seen this before? I’m really stumped.

Thanks in advance for any advice!
