Always get "fatal error message" when inserting Muffin-Builder Section?

Hey guys, 

Today I wanted to change some content on my website. I logged into wordpress, edited the page with muffin builder but when I hit the "update" button, this message occurs: 

Fatal error: Uncaught Error: [] operator not supported for strings in /home/.sites/149/site7278226/web/wp-content/themes/betheme/functions/builder/back.php:918 Stack trace: #0 /home/.sites/149/site7278226/web/wp-content/themes/betheme/functions/meta-portfolio.php(460): mfn_builder_save(2781) #1 /home/.sites/149/site7278226/web/wp-includes/class-wp-hook.php(288): mfn_portfolio_save_data(2781) #2 /home/.sites/149/site7278226/web/wp-includes/class-wp-hook.php(310): WP_Hook->apply_filters(NULL, Array) #3 /home/.sites/149/site7278226/web/wp-includes/plugin.php(453): WP_Hook->do_action(Array) #4 /home/.sites/149/site7278226/web/wp-includes/post.php(3581): do_action('save_post', 2781, Object(WP_Post), true) #5 /home/.sites/149/site7278226/web/wp-includes/post.php(3654): wp_insert_post(Array, false) #6 /home/.sites/149/site7278226/web/wp-admin/includes/post.php(377): wp_update_post(Array) #7 /home/.sites/149/site7278226/web/wp-admin/post.php(194): edit_post() #8 {main} thrown in /home/.sites/149/site7278226/web/wp-content/themes/betheme/functions/builder/back.php on line 918 

Could anyone tell me what to do?  

Thank you in advance!

Hey,
please disable all plugins and check again. It could be some plugin or server limits.
thanks

Hello, 

thank you for your quick response. 

I did so, but nevertheless, this error message still occurs  

I read somewhere else that it has to do with php7, but I do not know where/how to change that.

If you want to change the version of PHP then you will have to contact your hosting provider.
thanks
