Hi,
I’ve had same ‘AJAX call successful, internal saving process failed’ error.
I tried many things, as apparently such errors was when my table was more than 140 rows [ trying the memory on /etc/php.ini, or on wordpress config files ].
Finally (after setting up php logs in /etc/php.ini with display_errors=On),I found that I was having errors on /var/log/messages :

Mar 10 00:30:13 opvmw01 suhosin[15772]: ALERT – configured request variable value length limit exceeded – dropped variable ‘tablepress[data]’ (attacker ‘10.115.64.145’, file ‘/var/www/html/wordpress/wp-admin/admin-ajax.php’)

This is in fact not an attack, but tablepress sending too big data..
I then changed /etc/php.d/suhosin.ini adding such lines:

suhosin.get.max_value_length = 650000
suhosin.post.max_value_length = 650000
suhosin.request.max_value_length = 650000

I don’t know which one is fixing the defect, but this is working now for me.
Hope this will fix for you too..

PS: I’m also having below error in /var/log/messages, annoying but not blocking:

Mar 10 00:52:24 opvmw01 suhosin[15810]: ALERT – configured request variable name length limit exceeded – dropped variable ‘wordpress_admin_default_language_1765eceb4e6cdb9bbe2f78a15c23882a’ (attacker ‘10.115.64.145’, file ‘/var/www/html/wordpress/wp-admin/admin-ajax.php’)
