I recently tried to install the Extended Live Archive plugin. After uploading the files to the plugins folder, this error appeared over the list of the plugins in the plugins page.
Warning: file(/.../blogg/wp-content/plugins/af-extended-live-archive/af-extended-live-archive.php): failed to open stream: Permission denied in /.../blogg/wp-admin/admin-functions.php on line 962
Warning: implode(): Bad arguments. in /.../blogg/wp-admin/admin-functions.php on line 962
This is line 962 in admin-functions.php:
$plugin_data = implode('', file($plugin_file));
The plugin didn't show up in the list of plugins, and the only thing I could think of, was to make admin-functions.php writable by everyone (not anymore), but it didn't work.
As far as I now, I haven't done anything to the admin-functions.php file
Thus, what is wrong, and what can I do to make the plugin work?
Thank you for your time.
