I cleanup old dockers, and i rebuild the app, i restarted the server but nothing changed. Can you help me ?
Thank you

Do you have at least 2gb of swap set up on your server? If you do not, update can fail due to out of memory.


(Marco) #3

Could someone write a check during the update? If there’s not enough swap memory, then it doesn’t start the updating.

Hello

I have 4GB of RAM and 2GB of Swap… Swap is not yet used…

Edit : I updated again the app and now it works. Thank you !

I am also getting a white blank page following the latest update. http://comms.southsudanngoforum.org/
The site is showing using Safari but is not appearing in Chrome or Firefox
http://comms.southsudanngoforum.org/logs

Im not seeing any errors on the console, here’s the output from top.

I’ve tried appending ?preview-style=none but with no effect.

Any ideas?

Interesting - happening to me just now on an older Android phone and thought it was a site error, but maybe this is a general issue?

It appeared to be working with no issue until I logged into my site about 20-30 minutes ago. I thought it might have something to do with the scripts running when you log in (I was waiting to screencapture the “add to homescreen banner” prompt for the site instructions)

I am using a Galaxy S3 with the built-in browser


(Brianmcdonald) #8

I logged in using Safari and disabled custom styles which seems to do the trick.


(Robert McIntosh) #9

We disabled custom styles too and it seems to have fixed some loading issues but not all - the logo in the header no longer brings you to the home page


(Kane York) #10

Wow, uh, you’re using 700MB of swap. I think it’s time to add more RAM to that box.

Blank page issue happens to me as well.
After cleaning cache of my browsers, all of them show blank page now…


(Non-technical User) #12

Try doing the following. Rebuild the app via docker and If you are using a proxy like cloudflare, purge all cache. Do the same on your browser too. This fixed the blank page for me.

If it doesn’t work post your console errors if any on your browser.


(Wesley Chia Wei Lin) #13

I end up solve by setting app.yml, set version to stable instead of testpassed
and then ./launcher rebuild app

In my case, behind a reverse proxy, it was related to the pagespeed module which was enabled…
