This question already has an answer here:
All of a sudden when I insert a picture into a page, it shows an edit and a delete button above the image to the end user. These buttons take you to the default page. Also, now when I edit a page from the edit button at the top of each page and save, I get the following type of message after a lengthy wait.
Fatal error: Allowed memory size of 356515840 bytes exhausted (tried to allocate 523800 bytes) in /data/www/luna/sites/all/modules/token/token.module on line 767
I can edit and save if I select the page under Content.
