Re: 500 Errors (1and1 webhost)
I use 1and1 for a couple of my sites…
From what they tell me, 1and1 will not work with most wordpress or wordpress mu sites because they only allow php limited amount of memory.
You can change the memory in php.ini and if you use phpinfo it will show up as 64mb, but at the server level they have it configured for this:
These are the following restrictions on our “Linux shared business” hosting packages.
A process may only use a CPU at 100% for 6 seonds
A process may use a maximum of 12 mb of RAM
A maximum of 12 process to be run at any 1 time
They do have a shared developer package with a lil better memory, but you’ll probably still get the issues…
