Fatal Error message – AgentPress 2.0

Hi. This is my first post in a support form, so please excuse if I do something wrong.

I have an AgentPress 2.0 site and was trying to add a plug-in and received the following error message:

Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate 19456 bytes) in /hermes/waloraweb004/b152/moo.anthonyrealestatenet/wp-admin/includes/menu.php on line 38

I also get same error message now when trying to get into ADMIN and won’t let me in. I am a real estate broker, not a computer tech. so any help or suggestions are greatly appreciated.

Here is my site: https://www.AnthonyRealEstate.net

Thank you.
