Post Error Problem

Site: https://www.acnenodules.info/

I am restoring a wp blog due to problems with unusual characters appearing in the text of posts.

I removed the original blog from the server and re-installed using fantastico.

I am trying to add the first post, but half way through the post I am getting question marks appearing throughout the text. The first part of the post does not seem to be affected.

It doesnt seem to matter what I do, I cant get rid of the question marks. I have also tried to replace the textual content of the post in phpmyadmin, but when question marks appear again after saving.

Would appreciate any advice…. Thanks
