I have the cache file created, I’ve chmoded everything, this message shows up at the start of my most recent update on the dashboard and on the widget:
Warning: /home/XXXXXXX/public_html/cnk/cache/6d36c2d5db3186bfc719e2d9d289a992.spc is not writeable in /home/XXXXXX/public_html/cnk/wp-content/plugins/mytwitter/simplepie.inc on line 1623
It was trying to write the cache file in the folder “/home/XXXXXXX/public_html/cnk/cache”, but it was not able to write it there. This could be due to permissions settings. If you’re on unix, chmod the directory to 775.
