 * Hi,
 * I am receiving multiple fatal errors when I try to edit my archives page. The
   last time I was to update the page was October 31, 2019. When trying to update
   for November 30, 2019, the following errors started appearing:
    Fatal error: 
   Out of memory (allocated 547880960) (tried to allocate 1052672 bytes) in /homepages/
   46/d192996334/htdocs/XXXXXXX/XXXXX/wp-includes/wp-db.php on line 1995
 * Warning: call_user_func() expects parameter 1 to be a valid callback, no array
   or string given in /homepages/46/d192996334/htdocs/XXXXXXX/XXXXX/wp-includes/
   functions.php on line 3291
 * I do not have direct access to the cpanal and the host is unable to figure out
   the issue. The way I have been accessing the admin files is by using wp-file 
   manager that I keep uninstalling due to security concerns.
 * Suggestions to resolve this issue would be appreciated.
 * Thank you!
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fmultiple-fatal-errors-2%2F%3Foutput_format%3Dmd&locale=en_US)

 * Hi [@efran1526](https://wordpress.org/support/users/efran1526/) ,
 * I suspect there are many loop/process on that side, try to increase the PHP memory
   limit to 512MB (just in case).
 * if you can acces & edit wp-config.php, try to active the wp_debug so you can 
   see the exact error (it should be), here how to do:

 * 547880960 522,5 MEGA BYTES, you need more value than this 547880960+1052672= 
   523.50390625 MEGA BYTES
    [https://github.com/WordPress/WordPress/blob/4.2-branch/wp-includes/wp-db.php#L1995](https://github.com/WordPress/WordPress/blob/4.2-branch/wp-includes/wp-db.php#L1995)
   please lack information, WordPress version used, php in use if you are using 
   an original copy, you have a wordpress version modified by your hosting (ask 
   your hosting). On line 1995 I found correspondence from WordPress 4.2 to 5.3 
   in WordPress 4.2. for a complete understanding , i that the initial error is 
   in call_user_func exactly to that line 3291 of code (it means WordPress 5.3) 
   [https://github.com/WordPress/WordPress/blob/5.3-branch/wp-includes/functions.php#L3291](https://github.com/WordPress/WordPress/blob/5.3-branch/wp-includes/functions.php#L3291)
   If you have backups of the files and the database, simply use the php file_get_contents
   function with the local absolute path to recover the code. However you have 522
   MEGA BYTES in your database and for php there are too many, it can be a theme
   or plugin conflict, after the backup deactivate all the plugins and go to the
   default theme one of the twenty installable.

 * Thank you for the information but I just discovered that this particular page
   is corrupt. On the right side of page there is information that I never put on
   this page and i’m just now seeing it. [http://www.arvfd.ca/call-activity-archives/](http://www.arvfd.ca/call-activity-archives/)
 * Unless there is a tool that will allow me to access this page to edit it, I think
   I have no other choice other than recreate it.
 * Thank you again for your help.

 * can you share what’s on line /homepages/46/d192996334/htdocs/XXXXXXX/XXXXX/wp-
   includes/wp-db.php on line 1995? [https://github.com/WordPress/WordPress/blob/4.2-branch/wp-includes/wp-db.php#L1995](https://github.com/WordPress/WordPress/blob/4.2-branch/wp-includes/wp-db.php#L1995)
   
   I’m thinking that you have permission problems and unfortunately you can’t update
   correct via Dashboard. Ask your hosting what to do in this case.

 * ok you’re using WordPress 5.3
 *     ```
       //for administration
       define( 'WP_MAX_MEMORY_LIMIT', '1024M');
       ```

   otherwise if your hosting allows it you can use php.ini or htaccess, ask your
   hosting. see if this solves your problem

 * it is not a good idea to change the core because with the update it is restored
   to the current code.
    Obviously you can change the value `'256M'` to `'1024M'`
   also in default_constants.php but a good coding indicates to create the constants
   before the require_once wp-settings.php of the wp-config.php file. For other
