Unable to login to website

Hi.

I’m unable to login to my website anymore. I think this is caused by the WP-Super Cache plugin. Here is what I can see in the error log:

[09-Jan-2018 17:14:05 UTC] PHP Warning: include_once(/home/academie/public_html/wp-content/plugins/wp-super-cache/wp-cache-phase1.php): failed to open stream: No such file or directory in /home/academie/public_html/wp-content/advanced-cache.php on line 21

[09-Jan-2018 17:14:05 UTC] PHP Warning: include_once(): Failed opening ‘/home/academie/public_html/wp-content/plugins/wp-super-cache/wp-cache-phase1.php’ for inclusion (include_path=’.:/usr/local/php70/lib:/usr/lib/php:/usr/local/lib/php’) in /home/academie/public_html/wp-content/advanced-cache.php on line 21

I can’t access my dashboard to disable the plugin. Through ftp I tried renaming all folders related to wp-super-cache but no luck.

Any ideas ? Thanks
