Hi @nico2000, thanks for reaching out.
I can’t find any record of the precise error you’ve highlighted above to link it with a specific server platform, plugin, or host. Are you still running 7.10.5 on your site and just unable to update to the latest version?
I would firstly check in with your server administrator or hosting support to see if they can find any current problems with your site. Failing this, I can certainly try to look at general configuration like database/file permissions, connectivity etc. if you send us a diagnostic report to wftest @ wordfence . com so we can take a look at your configuration. Use the link at the top of the Wordfence > Tools > Diagnostics page. Then click on “Send Report by Email”. Please add your forum username where indicated and respond here after you have sent it.
NOTE: It should look as follows – Screenshot of Tools > Diagnostic > Send by Email
Thanks,
Peter.
