    I can’t login to my site and keep getting the following:

    Warning: Header may not contain more than a single header, new line detected in /home/incredip/public_html/Incrediplex/wp-login.php on line 411

    Some plugin or your theme may be causing this error, or a special combination of incompatible plugins.
    If you connect to your server via ftp, you may deactivate one plugin at a time by changing the name of their folders. The plugins are located in
    public_html/wp-content/plugins

    If deactivating most of your plugins won’t help, then you may need to force your site to revert to the standard theme:
    Upload the unzipped contents of twentyseventeen including the folder with this name to …wp-content/themes/ and rename the folder name of your active theme.

    This would hopefully allow you to log in again.
    Please let me know how you manage.
    Good luck.

    Thanks, but disabling plugins and the theme did not help.

    I solved my own issue. I found that somehow the MySQL table wp_options became corrupted. I had no backup of the database. I replaced the bad table by creating a new empty MySQL database on my server then uploading a new wordpress.zip using the file manager. I extracted the WordPress file and then installed WordPress to create new tables in the new MySQL database. I then exported the new wp_option table in the PHP MyAdin tool for the new WordPress and saved it to my local drive. I then dropped the MySQL table wp_options in the old WordPress database then imported the new wp_options table. Unfortunately, this meant I lost all my theme settings which had to be redone. It took a while, but at least I retained all my uploaded media files. I then created a backup of the database and the files and saved them on my local drive, and installed Updrafts Plus plugin and created a local backup. Always backup your database and files in case something like this happens!

    Wow. Good thing that this happened that early on, so you didn’t loose any content.
    Thanks for reporting back!
    Good luck!
