I am trying to load my website and receiving the following error on a blank white page:

Fatal error: Allowed memory size of 41943040 bytes exhausted (tried to allocate 12288 bytes) in /home/xxxx/public_html/wp-content/plugins/js_composer/include/classes/updaters/class-vc-updater.php on line 198


To fix this, simply place a .user.ini (yes, remember the leading dot!) text file in the root /public_html folder

Write the following line of code in the file:
memory_limit = 50000000M
