WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: Can’t Log in to my website back end., by t-p Your Artisan 0.2 theme seems to be the error. Your currently used theme is not in the wordpress.org/themes/ directory: https://wordpress.org/themes/search/Artisan/ If this was a custom theme, you may have to go back to your developer team and ask them to make the necessary change(s) to the theme. For pro or commercial product support please contact the author directly on their site. As the author is aware, commercial products are not supported in these forums. As you are their customer I am sure they will have no problem supporting you there. If you need immediate access to your dashboard, try switching to the unedited default Theme (Twenty Seventeen.) using FTP/ SFTP , or your web-host’s cPanel or whatever file management application your host provides (no Dashboard access required). Navigate to /wp-content/themes/ and switch to the default theme by renaming your current theme’s folder by adding “-old” to the end of the folder name. Alternately, you can remove other themes except the default theme (Twenty Sixteen.). That will force your site to use it. Reply To: Can’t Log in to my website back end.
