“The first image before I had changed the settings gives” should be:
<a href="https://muziektentenrotterdam.zigzap.nl/wp-content/uploads/2016/03/Kralingse-Ijsclub.jpg" rel="attachment wp-att-546"><img class="alignnone size-full wp-image-546" src="https://muziektentenrotterdam.zigzap.nl/wp-content/uploads/2016/03/Kralingse-Ijsclub.jpg" alt="Kralingse Ijsclub" width="1285" height="774" />
So </a><a href="https://muziektentenrotterdam.zigzap.nl/wp-content/uploads/2016/03/Kralingse-Ijsclub.jpg" rel="attachment wp-att-546">
disapeared and that part <ahref="https://muziektentenrotterdam.zigzap.nl/xxx" rel="attachment wp-att-xxx">
is not there anymore whenever I insert an image on whatever page.
Still don’t know how to fix this.
