I have nearly the same error message when I try to open the control panel index.php:
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to allocate 16896 bytes) in /mnt/ja2/01/795/00000000/htdocs/dritter/pm/lib/encoded.email.php on line 48
This looks to me, as if the 8MB my Server allocates for PHP are also not enough?!? My Provider Strato (one of the biggest and most inflexible in Europe) says, they won’t allocate more than that to my webspace package. What can I do? Do I have to go to another provider? Unfortunately I just bought a specific Domain for my Weblog @ Strato and payed the fee for one year today. I have an alternative provider who says they allocate 15 MB for PHP. But how much memory does pMachine really need? Is 15 enough? You should contain this information in you requirements for pMachine here: http://www.pmachine.com/expressionengine/requirements.php
