Like is not working

regardless of whether I'm logged in as an admin, a normal user or anonymous it does't work.
As an anonymous only the hart color changes to red and it grows a little bit and »Like« isn't visible as a link.
As a user I can click the »like« and the modal shows the following:

Do you nneed more info?

Okay thanx for the advice. There are no tables
• votingapi_vote
• votingapi_result
in the db.

Voting API is activated by install process with Demo content and also the social like module is activated.
I configured it on
.../admin/config/search/votingapi/like_and_dislike
Do you have a suggestion what to do?

Sorry, I looked into wrong db.
The tables
• votingapi_vote
• votingapi_result
are existing in the db. And what should I find in there?

On the other hand: I tried another install – fresh and local.
And also I got the same issue there: its not possible to like.
I then installed the blog module and nothing else and found the following similar (not identical) error like in opening statement.
So it seems that this is a generally issue.
Maybe someone else could proove this?

In a new fresh install of social-8.x-4.7 I applied the patch #52 of https://www.drupal.org/project/drupal/issues/2663316
and the notice from above „Array to string conversion....“ which results by clicking a like button was gone.

But again as before: no new like is shown in the modal or counted in the db.

Please help !!

Okay, I installed a fresh social-8.x-4.8 english version – the same result: I can see the voting results in the demo content (and in the db) but the »Like« of mine isn't added.
Then I installed a fresh social-8.x-4.8 without demo content – same issue. Both db voting fields still stay empty if I use the like button.
Other ideas?

Hi,
I tried the fresh installs via composer first on my local mac and then also on a shared host with:
Datenbankserver-Version: MySQL 5.6.40
Perl-Version: 5.20.2
Python-Version: 2.7.9
ImageMagick-Version: 6.8.9-9

Both with same results.

See screenshots which are showing that its a POST

Do you need more info?

One step further:
Like and dislike and OpenSocial are working together only by using like_and_dislike 8.x-1.0-alpha2.
Not with alpha-3 and not with beta-1.
I thing its an ajax modal issue.
