Configuring PS Back Office

[Joe Germann]

I installed PS 1.7 to test and develop a replacement for our existing 1.6.

My test site domain is running PHP 7.3 as recommended and the install goes well right up to the very end.  I deleted /install like recommended and then clicked on "Manage your store" button to get into the Admin area.  The login seems to go fine but then gives me the attached page.  I'm thinking it as to do with the new site being turned off in ../admin/performance/maintenance I have been unable to set Admin to know my development URL.

I'm totally stuck on figuring out a solution.

How can I get past this stumbling block and be able to log in to the back office section?

Thanks,

Joe
