Media library problem

Good morning,
Since the update of Enfold 4.4.0 (today I have updated to enfold 4.4.1 and the problem continues), I can not see the media library in grid format, and editing a page when inserting an image does not show me the images. He stays thinking.

I’ve been trying to remove all the plugins, remove performance optimizations from Enfold, looking at PHP errors, apache …. nothing does not work.

I get this error in error.log:
[Tue Jun 05 09:49:51.883835 2018] [proxy_fcgi: error] [pid 7826] [client 94.130.216.183:47232] AH01071: Got error ‘PHP message: PHP Warning: session_start (): Can not send session cookie – headers already sent by (output started at /home/admin4/public_html/danysoft.com/wp-content/themes/enfold-child/functions.php:1) in /home/admin4/public_html/danysoft.com/wp-content/themes /enfold/config-templatebuilder/avia-shortcodes/masonry_entries/masonry_entries.php on line 56 \ nPHP message: PHP Warning: session_start (): Can not send session cache limiter – headers already sent (output started at / home / admin4 / public_html / danysoft.com/wp-content/themes/enfold-child/functions.php:1) in /home/admin4/public_html/danysoft.com/wp-content/themes/enfold/config-templatebuilder/avia-shortcodes/masonry_entries/ masonry_entries.php on line 56 \ n ‘

I tried to put (read in a post):
add_theme_support (‘avia_no_session_support’);

And nothing, still does not work.

Help, please.
Thank you.
