batch adding has always been working for me, but now I created an album, and uploaded over 1000 pictures, which i wanted to batch add, and got this error.

I don't know what a server error log is ... What should I do ? :-[
You're overloading the server. Upload less files in one go, preferably split those 1000 files into sub-folders. If this doesn't help, take a look at the mass import plugin.
For details, the same recommendation that supporters reply to all threads on this board applies to you as well: do exactly as suggested in the upload troubleshooting section of the docs if you want support on uploading issues.
