Fatal Error – PLEASE HELP!

https://thepracticeroom.net/examples

That page is being executed by a plugin – exec-PHP. My programmer had trouble with the session data and had to alter the wp-config file so that when the next button was clicked it would remember the session and find the next example. We used the solution found here:

Worked like a charm and the page was humming along swimmingly.

Now suddenly on my macbook pro it’s throwing this error:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 64 bytes) in /usr/home/erinlowell/public_html/thepracticeroom.net/wp-includes/pomo/mo.php on line 227

It works fine on my programmers computer and fine on my ipad. So I don’t know why it’s not working on my macbook. I’ve tried quitting the browser and reopening, no luck. I’ve tried clearing the cache, no luck. At one point, I had trouble getting into wp-admin

I have no idea what to do. Any help would be appreciated.
