bellini13 Posted August 4, 2014 Share Posted August 4, 2014 i would disable the pagecache module by deleting it from the modules folder. it is likely not compatible with PS v1.6. see if that addresses the issue. also you can enable debug mode by enabling _PS_MODE_DEV_ in /config/defines.inc.php. Instead of a blank white page, you will see the error message Link to comment Share on other sites More sharing options...
Kstyle001 Posted August 4, 2014 Share Posted August 4, 2014 Same as you, blank front-office. Link to comment Share on other sites More sharing options...
bellini13 Posted August 4, 2014 Share Posted August 4, 2014 and did you bother to follow the instructions I provided directly above your post to determine what the error is? Link to comment Share on other sites More sharing options...
peter4661 Posted August 4, 2014 Author Share Posted August 4, 2014 It turned out we did not had latest revision of module Pagecache. After we installed latest module version and ran upgrade to PS 1.6.0.9 problem was solved. Link to comment Share on other sites More sharing options...
benjamin utterback Posted August 4, 2014 Share Posted August 4, 2014 It turned out we did not had latest revision of module Pagecache. After we installed latest module version and ran upgrade to PS 1.6.0.9 problem was solved. Quick question, you used the Autoupgrade module? You installed the latest version of pagecache (this module?» http://addons.prestashop.com/en/seo-prestashop-modules/7939-page-cache.html ) Did you install the latest version of pagecache via FTP? Do you have a link to your upgraded store? Link to comment Share on other sites More sharing options...

Do you have a link to your upgraded store? We did not use auto upgrade module, but upload / extract via server admin panel. We uninstalled pagecache module. Ran ugrade to PS 1.6.0.9 succesfully. And reinstalled latest version of pagecache module. With thanks for the support we did get from developer Joe Martin. Sofar everything works fine, still work to fine tune the site .

bellini13 Posted August 4, 2014 Share Posted August 4, 2014 Ran ugrade to PS 1.6.0.9 I think Ben means, did you use the autoupgrade module to upgrade Prestashop to PS 1.6.0.9. Link to comment Share on other sites More sharing options...
peter4661 Posted August 5, 2014 Author Share Posted August 5, 2014 Confirm. we used 1 click upgrade to get the upgrade to P.S. 1.6.0.9. Link to comment Share on other sites More sharing options...
