Every Page says There was a problem displaying the preview

Posted on by JonDev01

After no changes I can think of every page on my portal is giving "There was a problem displaying the preview". Is there any way to view or edit code to determine the issue?

The only thing I can think of is about 4 hours ago I copied css into a Theme under Edit CSS and it didn't seem to take affect so I decided to ignore it for now and deal with it later. Other than that I was working on a particular page, got up for 2-3 minutes and when I came back no page will load. I'm pretty new to the environment so I don't know if this is an over all power apps portals issue or if it's something I did.

No luck. I forgot to mention I am using a Trial portal if that has any effect on the problem.

Just check the portal expiry date. You can check this info in make.powerapps.com > click apps and check the type as portal

You can see expiry date.

It expires 18 days from now. The other thing I did yesterday was to set up 2 factor auth on my account. That was shortly before the Portal designer stopped working. I am still able to browse to the pages I am only prevented from using the designer.

Because this is a trial environment and I need to keep moving I have decided to abandon this environment and to use one my company has previously set up for a prior project. Thanks for your help.

Hi @JonDev01

It is clear that the portal has expired already. So the portal studio error is expected. The simple solution is to delete the existing portal and create a new one. When creating a new make sure you select "Choose From existing website Record" and pick the website.

Trust me your data will be restored and all your pages will be recovered.

Bonus: Instead of spinning trial environment. you can get your own development environment for one year. Adding link below

Hope it helps.
