Blank pages in 1.6.1.0 Back Office

[rbalva01]

Hello dear fellow PrestaShop users/devs, I'll tell you my story:

 

I've recently installed PrestaShop 1.6.1.0, running on Apache 2.4.12 and PHP 5.6.11. on a local Windows environment a week ago.

 

Testing Back Office functionality I've encountered 2 main issues:

1. Several pages (dashboard, translations...) show only a blank page after loading for 30-40 seconds.
2. Overall, BO is pretty slow, with loading times being 25 seconds avg.

What i've tried so far, reading other forum entries:

• Enabling error reporting: still blank page.
• Checking PHP error log: no errors relating to these blank pages.
• Uninstall, delete files, database and any configurations, reinstall: still the same problems.
• Editing php configurations (max execution time, max input time, both to 1000, assigned 256M to PHP): nothing different happened.
• Disconnect Ethernet cable: worked like a charm, <5 seconds load times and no blank pages...but this is more like an ugly, non-practical-in-any-live-site workaround.

Front Office works really nice, no complaints there, but Back Office is a whole different story. The long loading times would be bearable...if the pages finally loaded.

 

Any of you have the slightest idea of why disconnecting the cable make everything work alright? It makes no sense to me since this PS instance is on a totally local environment.

 

Any of your assistance or advise is highly appreciated, thanks in advance.

Hi,

 

Do you have slow internet connection on your local machine because back-office might be connecting to server as per your message (Disconnect Ethernet cable: worked like a charm)

 

I am using on local linux machine for prestashop version 1.5 and 1.6 and it is working fast.Hosted prestashop of web hosting works good as well.

I'm not really sure if Prestashop looks for updates or something, but definitely it tries to connect somewhere on the Internet. I asked around in the company I work for and it turns out that Internet service gets through proxy servers, so that may be the reason of the long loading times or not loading at all. I'm now using PS 1.6.0.14 per our clients request and loading times are now not so long (10 seconds avg), so this problem is kind of solved.
