fatal error, called to undefined function, wp_cache (3 posts)

    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.

    You can get fresh copies of WordPress from here: http://wordpress.org/download/release-archive/
