Upon logging into the Admin today, I received the following error.

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 24 bytes) in /home/[clientname]/public_html/sapphire/thirdparty/jsmin/JSMin.php on line 144. I increased the hosting memory allocation, but this hasn't helped. What could be the problem?

Here is what is on line 144 in this file:

142  if ($c === null) {
143      if ($this->inputIndex < $this->inputLength) {
144        $c = $this->input[$this->inputIndex];
145  $this->inputIndex += 1;

Just need to increase the memory more. SilverStripe is quite resource hungry. You only had 32mb, Try setting it much higher - 64mb at least.
