 * I am managing a website for a friend. Unfortunately his current provider works
   with an outdated PH version (5.4), so I come across a lot of problems. The latest
   upgrade of nextGEN Gallery caused the WP backend to crash (error 500). According
   to the error log, fatal errors were caused by the latest ngg version. The older
   one worked, therefore I tried to downgrade ngg. But now I can’t activate it. 
   It says:
 * > Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate
   > 72 bytes) in /home/www/wordpress/wp-content/plugins/nextgen-gallery/products/
   > photocrati_nextgen/modules/nextgen_admin/package.module.nextgen_admin.php on
   > line 1079
 * What can I do to solve the problem?
 * My friend is tied to his provider for half a year, and PHP upgrades will not 
   come until end of 2017. 🙁
 * Thanks in advance!

 * [@iriskammerer](https://wordpress.org/support/users/iriskammerer/) – The message
   you are seeing is pointing to a low PHP Memory Limit, this might be something
   you can work out with the web hosting service to increase to something more suitable
   to a robust WordPress installation. I would suggest pushing for at least a PHP
   Memory Limit of 128MB (preferably 256MB).
 * Thanks!
