Page gone blank with update

Hello i just updated the theme and the whole website went blank, nothing opens not even wp admin site, my site is

http://optimusinformativo.com/

I updated via Theme update with envato toolkit, I also went to my files and say this files which seem extremly rare:

loop-single-1.php and keeps repeating to 13

single_template_1.php and keeps repeating to 13

I just deactivated the wp-super cache plugin and i can acces know, but the theme wont read the revolution slide i had and won’t respect the columns set before, for the revolution slider says: [vc_row el_class=”td-slider-row”][vc_column tdc_css=”eyJhbGwiOnsibWFyZ2luLWJvdHRvbSI6IjIwIn19″][rev_slider alias=”newspaper-politics”][/vc_column][/vc_row][vc_row el_class=”td-news-ticker”][vc_column] which was the code, and for the content columns says:[/vc_column][/vc_row][vc_row el_class=”td-ss-row”][vc_column width=”2/3″]

I had to deactivate all the plugins via FTP to make it work and realized the WP Super Cache tested plugin was causing conflict, still don’t know why but everytime i activate it, my site crashes

Hello Bogdan, i’ve tried in another subdomain and it works perfect, but in main one won’t. I´ve also tried wihtout any other plugin but still crashes everytime i install or activate wp super cache

Could you help me up?

I just followed this instructions and it’s working again:

First, on your WP root directory, edit the file wp-config.php. If you find these lines:

define(‘WP_CACHE’, true); //Added by WP-Cache Manager
define( ‘WPCACHEHOME’, ‘/your-site-root-directory/wp-content/plugins/wp-super-cache/’ ); //Added by WP-Cache Manager

delete them.

And if the directory /wp-content/plugins/wp-super-cache is still there, delete it, too.

Then use FTP or your control panel file manager to delete the full directory /wp-content/cache and /wp-content/wp-cache-config.php and /wp-content/advanced-cache.php.
