 * My blog has been running for almost a year with no problems, then all of a sudden
   I get an error message, but I have not changed anything or even posted recently.
 * Original error
    Fatal error call to undefined function wp_cache_init(); on line
   133 in wp-settings.php
 * I do some reading and research and find the advice to add the line
 * (‘ENABLE_CACHE’, true);
 * Above the line wp_cache_init(); in the wp_settings.php file
 * I do this and now I get this error:
    Parse error: syntax error, unexpected ‘,’
   in /home/merrfit8/public_html/wp-settings.php on line 131
 * I remove the comma from before the word true);
 * I now get the error:
 * Parse error: syntax error, unexpected T_STRING in /home/merrfit8/public_html/
   wp-settings.php on line 131
 * (Which from all I have read indicates a missing apostrophe or semi-colon. )
 * Upon further reading, I now edited this line in wp-settings.php to read
 * Define (‘ENABLE_CACHE’, true);
 * I added a directory called cache under wp-content and gave the permissions 777
 * The error message comes back to;
 * Fatal error: Call to undefined function wp_cache_init() in /home/merrfit8/public_html/
   wp-settings.php on line 131
 * Can anybody give me any assistance? My webhost said I need to re-install wordpress.
   
   Thanks so much.

 * 1) Stop editing files.
    2) Undo any and all changes you made to that file. Remove
   the cache directory you made, you don’t need it. 3) Get a fresh, clean copy of
   WordPress and make sure that you’re not missing any files from your installation.
   Specifically, check to make sure all files in wp-includes are there.
