I'm not sure what else to do. I filed one bug report about a memory issue, which turned into a /_cache/_app/content.php permissions issue, and now we're back to a memory issue again.
My memory has been upped on Dreamhost to 128M, but it looks like that's still not enough. I'm now getting this issue:
"Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 109 bytes) in /home/harmar12/curiousrat.com/_app/core/content/contentset.php on line 984"
How much memory do I need to run my site now? I haven't been able to upgrade to anything beyond 1.8.4 because I keep running into these kinds of problems.
