I was running 1.1.4 fine with no problems. I disabled all add-ons, and then uploaded the files for 1.2.2 upgrade. Started the process, and it gets to the point of 'rebuilding templates....' and then crashs with this message: I read thru all the other threads, and my server is running the latest mysql and php, and i tried increasing the memory size and packet size as suggested, but that is no help, still gives me an error. Others suggest I run 'rebuild master data', but that option is gone now that I started the upgrade process, my board is also locked off because of that, so I have no options in admincp except to finish the upgrade. Is there a way, I can return to 1.1.4 and get 'rebuild master data' back and try the upgrade again, incase it is failing because of my customized templates? Thanks.
