Sorry folks I just updated to WordPress 6.3 and something went wrong.
I’m already on it and hope to fix it I hope soon since my html is very limited and I do have to figure out how to enable workarounds I found on the web.
The posts are still there and inside them evrything works alright. It’s only the excerpts shown at the home page which are broken.
As soon as I have figured all out I shall be removing this message.
Thank you very much for your comprehension!
