An unexpected error occurred

Try a few basic troubleshooting steps:
– Try deactivating ALL plugins temporarily to see if this resolves the problem. If this works, re-activate them individually (one-by-one) to find the problematic plugin(s). If you can’t get into your admin dashboard, try deactivating via FTP or SFTP or whatever file management application your host provides. Also remember to deactivate any plugins in the mu-plugins folder. The easiest way is to rename that folder to mu-plugins-old.
– If that does not resolve the issue, try switching to the unedited default Twenty Fourteen Theme for a moment using the WP dashboard to rule out any theme-specific issue. If you don’t have access to your admin area, you can switch to the default theme by renaming your current theme’s folder in wp-content/themes and adding “-old” to the end of the folder name using via FTP or SFTP or whatever file management application your host provides. Alternately, you can remove other themes except the default theme. That will force your site to use it.
– If above steps do not resolve the issue, try resetting the plugins foldervia FTP or SFTP or whatever file management application your host provides. Sometimes, an apparently inactive plugin can still cause problems (because the hooks remain unless plugins completely removed or some plugins stick around in cached files. So by renaming the folder, you break them and force them inactive).
– If all the above steps do not resolve the issue, try MANUALLY re-uploading all files and folders EXCEPT the wp-config.php file and the /wp-content/ directory from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones. Read the Manual Update directions first!

Thank you, Tara. I’ll give these a try. I’m not sure that I fully understand how to do all these things but hopefully I won’t have to try them all ??

You may also need to contact your hosting provider, because the following error:

>> WordPress could not establish a secure connection to www.remarpro.com.

This points to a server related issue, most likely related to the server’s resolver configuration. Your hosting provider should understand this wording.

Good luck!

Thank you, John.
