Hello 000webhost users ..
Same problem with me , but I’ve fixed it
“Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 8192 bytes) in /home/axxxxxxx/public_html/wp-content/plugins/facebook/facebook.php on line 1″
1. Once you installed the facebook plugin and when you activate the plugin you see Error message , Now Open FileZilla and Go to remote site “wp-content/plugins/facebook” there you see index.php , right click on it and click on “view/edit”, put php_value memory_limit 128M on top
Now save it ..
and Do it for all plugin you you want .. just open index.php and add php_value memory_limit 128M on top.
2. Add this line to your wp-config.php file to increase allocated memory to PHP:
define(’WP_MEMORY_LIMIT’, ‘256M’);
now save it … done !!!!
same you can do it for all plugins 🙂 just download them or install them , and edit index.php in particular plugin folder
