Related Items Extended error After installation

you have identified what is causing the problem?
do you think we will find a solution to the problem?
Thanks!!!

Thanks!!!

The first article ( adapokrites.gr/adapokrites/ksenos-typos/...odoi-pros-tin-evropi ) was missing, read more in the first paragraph of the article
I added it and activated the article.

Article 2 ( adapokrites.gr/adapokrites/diethneis-eid...eno-kentrou-ypodoxis ) plays normally.

But there is still a problem in other articles.
For example
adapokrites.gr/adapokrites/diethneis-eid...ki-ekklisia-sti-lyon

adapokrites.gr/adapokrites/diethneis-eid...asma-tou-tyfona-goni

adapokrites.gr/adapokrites/diethneis-eid...kataggellei-i-unicef

adapokrites.gr/adapokrites/diethneis-eid...diadiloton-varkeloni

and many more...


NOTE
There are 30,000 articles of which about 5,000 do not have photos. (unfortunately lost in the migration process)
Also columnists often forget to add read more.
But I do not understand that such a thing can create such a serious problem in the operation of the extension.

With the same default existing extension does not create any problem in the Website,but
It is simply very poorly made in the results it presents. SHOWS IRRELEVANT ARTICLES

I will be very happy if you find the solution to the problem so I can use your extension
