Did a search as to why my website also “lost” the www in the site URL after I had entered it in a browser. I cam across a post here that stated to a person asking a similar question:

You should also double-check the “Site address (URL)” in General Settings in your WordPress admin panel and make sure the “www” is there.

Well, I got the “www” back by changing the text in the wordpress admin panel. When I go to view the site I am working on it is there! Great! But… I can no longer log into the wp-admin location.

I have full access to the hosting account if I need to …

Can anyone help me get back into the admin panel of my site?

Thanks,
Mike
