Vitazzz Posted July 4, 2015 Share Posted July 4, 2015 (edited) I was working with my PS without any issues on shared server. Recently I've moved to a VPS. Everything seemed to be working, but I encountered issues with adding new content. For instance, if I add new manufacturer, or new category, or attributes, I can see them in corresponding menus. But if I go, let's say, and edit the product, I can't see my new manufacturer and can't assign it. If I go to new category in front office, I get 404 error. If I go to product combinations, I can't assign new attribute since it does not appear. BUT! After I reboot my server, all these things become visible and working (and i even can create new and see them) but in few next hours I will become unable to add and see new things again. I believe this is something related to DB. As far as I understand, new values are saved in DB but Prestashop does not always receive them back. And this happens only after some amount of time after last reboot. Also these issue happen only to certain things. So, for instance, new products and new orders are created and visible without problems. Again, this is not a fresh installation, but my old shared server with PS still runs without such issues. I've never seen them on a shared server. Edited July 4, 2015 by Vitazzz (see edit history) Link to comment Share on other sites More sharing options...
Krystian Podemski Posted July 4, 2015 Share Posted July 4, 2015 Maybe this is related to some caching mechanism enabled on your VPS? Link to comment Share on other sites More sharing options...
Vitazzz Posted July 4, 2015 Author Share Posted July 4, 2015 (edited) I only have APC as an external cache enabled on my server. It is PHP cache, so I don't think if this can have any impact.

Krystian Podemski Posted July 4, 2015 Share Posted July 4, 2015 And this can be a unfortunately a reason, check: http://forge.prestashop.com/browse/PSCSX-6015 for me APC causes only problems with few mechanisms and after adding new product or cms page everything is ok however in some cases it works like in your case Link to comment Share on other sites More sharing options...
selectshop.at Posted July 4, 2015 Share Posted July 4, 2015 And how many RAM ? Also RAM is a cache. If you don't use the whole RAM and you will have 32 GB, so the cache renews about all 3 days only. You should search the problem on the caching system of your server. Link to comment Share on other sites More sharing options...
selectshop.at Posted July 4, 2015 Share Posted July 4, 2015 BTW. APC ist not supported anymore if you are using php 5.5., cause for all servers with this php version they are configured with opcache, which is faster than APC. Take also a look into this: http://forge.prestashop.com/browse/PSCSX-5997 and this topic https://www.prestashop.com/forums/topic/448978-prestashop-1610-a-new-level-of-performances/ Link to comment Share on other sites More sharing options...
