Installation on WP 4.9.6 multisite. The sites are not listed

[rvencu]

Therefore I cannot add any site to the project. @ammmze is there a fix available for this problem?

Running on PHP 7,0 and from error_log I could extract this (sorry for the localization issue)

I added the missing column and some text inside it. Still the blogs are not listed and the error_log now shows this
