Hi Stiofan,
Thanks a lot for taking a look and your advice.
Sorry, but I don’t know how to do what you have asked.
I have disabled my Wordfence security plugin but that doesn’t seem to make any difference.
Could you give me a little bit more help as to how exactly I should or could find out what is causing the problem.
Should I contact my hosting company to check the server security?
Thanks,
Adam
