PHP Errors

I am no longer able to edit contacts. When I click on the edit button, it simply times out. I checked my logs and the below is what it says,

[12-Nov-2016 06:52:57 UTC] PHP Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 64 bytes) in /mnt/target03/341221/383375/www.myserverdummyaddress.com/web/content/l/wp-includes/wp-db.php on line 2409

It seemed to start after I installed the plugins and activated the social integration features: facebook, linkedin, twitter, rackspace and outlook. Since then I have unpublished them all, but I am still getting the same problem. Anybody had this same problem
