Allocated memory size exhausted

Hello,

I am trying to search for a media URL: https://www.mysite.com/wp-content/uploads/2014/10/player.gif – but I am getting this error:

“Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 123208231 bytes) in /home/myaccount/public_html/mysite.com/wp-content/plugins/search-and-replace/search-and-replace.php on line 718”

Can you help me with this, please?

Also, please tell me how to replace this URL (when the search function will show me the results instead of the error) – do I need to select an option from the list, or to leave them blank, all of them?

Thank you & Regards,
Oli
