 * Hello,
    I tried to login to my wordpress site, with my old password and i get
   the following error:
 * Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate
   5867257 bytes) in /home/content/21/6601321/html/MYSITENAME.com/wp-includes/wp-
   db.php on line 1033
 * why is this happening? what is this? how can i fix?
 * it only happens when i type my old passwords or something very similar to them.
   doesnt happen if i try something else random. i am also able to login with my
   new correct password
 * also do i need to clean up somewhere in my mysql db? it says exhausted…

 * Put this line in your wp-config.php:
 * `define("WP_MEMORY_LIMIT", 128);`
 * And ask your host to increase your max_input_vars in your php.ini file from 1000(
   standard) to like 5000 or at least 3000.
 * Why would you try to use an old password, anyway?

 * what does this do:
 * define(“WP_MEMORY_LIMIT”, 128);
 * and why do i ask them to increase size?
 * and in my database is somewhere full of unnecessary data and do i need to clean
   up somewhere?
