Enable debug mode to see the actual error, check your server error logs, ow_logs folder/error_logs file for anything related to the time when you started to have the issue. We need an actual error, then paste it here, so we could assist you 

The only error I get is this when I use the desktop version. No error on the mobile version, just a BLANK page.

Message:Undefined index: hostFile:/var/zpanel/hostdata/sdcd/public_html/sdcd_dk/ow_core/request.phpLine:214

I have the same problem :-(

I have same problem,but in my case (internal server error) 

here my post http://www.oxwall.org/forum/topic/40828

Ole, Make sure there's a mobile folder for the theme you're using, please share your url, keep debug mode to true

Layth, please see Tasia's reply. 

I use Macabre theme. Tried with other themes and is the same :-( 

ross, can I message you the url other details? 

Yes, PM me your CPanel and admin access details

Jozko, you have disabled mobile version in the admin panel, see screenshot I sent you. 

yes, i dissabled it because there was blank page (to not confuse my usres).

clear browser cache, as you can see from the screenshots I sent you mobile version loads properly. 

Still the same :-(

trying to reach mobile version via admin/mobile/index (attachment)

and from the bottom menu

Oh, ok, I see what you mean, please give me some time. 

ok

Jozko, We have fixed it on your website, it was due to the php you're using seems like it was a custom build, which is why there were some discrepancies in the php syntax. 

Ole, Layth, what php version do you have on your server?

I have php 5.3

When debug true same error (internal server error)

Do you have e500.php in the URL? if not then it is some server related issue, you need to check your apache error logs to find out the actual error or contact your hosting provider to resolve it. 

Yes ,i have e500.php in root, i will contact hosing provider and back to post reply

i have this error
