Help! I'm attempting to convert over all my image galleries from an old v1.3-cvs-rc4 to the latest Gallery v2.3. I'm getting these errors when I hit the "import button":

It doesn't appear that I'm bumping up against memory size issues. I should add that the g2data directory is world-writable, and writable by the web server user.

Can the G1->G2 import tool handle something this old? Also, I should reveal too that I was hitting an earlier error, where the converter was reporting that it could not find the file "photos.dat" in the Gallery g1 album directory. That file did not exist in my version of Gallery1 and I surmised that it might be looking for album.dat so I symlinked the file; i.e. photos.dat->album.dat in each album folder. That got me one step further in the import process.

I may try upgrading my v1.3 to a v1.5 or something that's a little newer and see if that helps.

Can anyone shed light on this? Thanks!

Phil

Dear jmullan:

I'm happy to report that upgrading to 1.5 first fixed the problem. Thanks for your suggestion!
