Issues adding dashlets to 7.6.1 fresh install

Hello, I have installed suite crm (vers 7.6.1) with mariadb on both Centos 6 and Centos 7 now because I cannot add dashlets, with permissions set

chmod -R 777 /var/www/

Everything seems to work, and I have ran the quick check and repair, as well as the desklet flush with no help whatsoever.

I would like to make this work on Centos 7, but by default the version is 6.4.4, which had a bug. So I created a new VM on Centos 6, but I am having the same issue on Centos 6.

only errors I see in the error log are:

I also copied the /var/www contents to the new server, and pointed to a server I inserted the database into, the site comes up no problem, but I cannot add dashlets.

Any help is appreciated, even paid to get this fixed up if need be. But, I am a seasoned linux veteran.
