Installation of rc4 stops

Which type of installation is that? Standard or demo?

We're working on fixing the bugs asap.

Had today the same problem.
Happens when in the beginning demo installation is selected.
With the standard installation and adding the demo content later no issue.
Except for installation it is best to disable all php timeouts it needs really long.

I am currently having the same error when installing '7.x-1.0' version.
I downloaded the zip, extracted it to my 'Sites' directory and changed it to use a 'docroot' setup. I then started a demo install and it went most of the way through before receiving this error. (not sure how far exactly it got as I stepped away)
I am on Windows 10 and using WampServer64.

Can you try installing it again but this time do not install the demo content? Uncheck the install demo content checkbox when it asks you to select features.

I was able to get through the install, and all in all, I'm pleased with Open Restaurant; but I did get errors in the install process. They all seem to be related to the Migrate process, and I'm finding issues resulting from it. For example:

The background image of the footer isn't showing up.
I've got items on the Migrate list; "default" shows "Importing" but isn't moving, and hasn't for over a day now. And "Restaurant Menu demo content" is showing "Import incomplete; not currently running."

I've also encountered an issue with the slider on the front page. I went in and replaced the default slide, and it went fine. I added a second slide, and when it would switch to that one, it wouldn't show a picture at all, just a white background. I thought perhaps it was something to do with the size of the image, so I removed it and replaced it with a different image, and now the frontpage slider shows no images at all. i get the two dots for the two images, and I can see the left and right arrows, and the dots will move back and forth as I click the arrows, but i see no images at all. I removed "frontpage slider" and replaced it with "news slider", which of course shows the news page image, but it appears to be working. I'm not sure how to reset/refresh the front page slider so that it'll work properly.

I'm left wondering what underlying problems I haven't found, due to install problems. is an update coming soon?

More to findings from above:

I'm not sure if this is an OR issue or a Panopoly issue, but I find with the Slideshows, if I remove the caption, the entire slideshow disappears/doesn't work. I attempted to take the caption out, so that I would just have the photos, and when I save and view, there's no slideshow. When I go back and replace the caption, the slideshow reappears.

Brian, can you open a new issue for the slideshow bugs please?

Sure. I wasn't sure if this was all related to installation issues or not.

Same problem with installation demo type.

Reinstall with the standard option and installation succeed, however I got some not blocking messages in the last two steps of the installation:

Passing an empty first parameter to a migration constructor is now deprecated - pass through the arguments array passed to the leaf class instead.

We fixed the migration parameter error in the latest dev. We'll tag a new release soon.

Open Restaurant 7.x-1.11 released. Please update. Marking this as fixed.
