Danke!
Ich hatte Yoast mal deaktiviert, aber es macht keinen Unterschied, die Spalten werden auch dann in der gleichen Weise zusammengeschoben
until today i didn’t have a trackback uri at the end of my posts and trackbacks were never sent.
After adding a trackback uri for my own articles, the sending of trackbacks suddenly started to work.
I wasn’t actually expecting this 🙂
Maybe someone else has got the same problem and this solution might help?
