 * I’m getting a fatal error with a basic setup that uses two languages (EN/FR).
   I’ve set up pages for both languages, but trying to change results in the following
   site-crashing error:
 * Fatal error: Allowed memory size of 33554432 bytes exhausted (tried to allocate
   78 bytes) in /usr/home/path_to_wordpress/wp-includes/pomo/mo.php on line 219

 * It seems that you are running into low memory. If you can, try increasing memory
   in php.ini. Are you using a lot of plugins ? Polylang does not use much memory
   compared to other similar plugins.

 * Ok, I had to increase the memory in my php.ini, as well as in my wp-config.php
   file. Here’s another forum post that helped with the latter: [LINK](http://wordpress.org/support/topic/getting-fatal-error-pomomophp-during-instalation?replies=5)

 * Unfortunately, non-English usage increases quite a lot the time loading and the
   memory usage (almost 5Mb on admin side according to my experience). This is due
   to the fact that WordPress loads (on every pages) the complete mo file containing
   all strings (almost 3500 strings for WordPress only and you have to add those
   of plugins + theme…)
