Blank screen - memcache problems

[dolphspeed99]

Hello,

 

As lots of you did, I also get a blank screen. It used to appear every 5-6 clicks and everytime I used to place an order and after refreshing the page, it would load the correct page. But after I logged out of my FO account, the blank screen appeared and I can't see the site anymore, no matter what I do. I turned on the error reporting and I get this error:

Fatal error: Call to a member function set() on a non-object in /home/steroizi/public_html/classes/cache/CacheMemcache.php on line 156

 

Under Advanced Parameters - Peformance, the last option is about Caching and it was set up by default Memcache but I can't change it. When I try to change to file system cache, I get the same fatal error in BO too. I also tried regenerating htaccess file, turned off smarty cache, activated Force Compile, I even copied the original cachememcache.php file from instalation folder ... nothing seems to work. Any advice?

 

When I try to change from memcache to file system cache, I get this error:

Warning: MemcachePool::set(): No servers added to memcache connection in /home/steroizi/public_html/classes/cache/CacheMemcache.php on line 156

Warning: Cannot modify header information - headers already sent by (output started at /home/steroizi/public_html/classes/cache/CacheMemcache.php:156) in /home/steroizi/public_html/classes/Tools.php on line 141

 

My server does not support MemCache.

Finally, I managed to fix this, but the problem is far from being solved. After trying again and again, I managed to disable the use of memcache, so under BO Advanced Parameters - Peformance, the last option is about Caching and I turned it off. Then the error would change in frontend to a problem in public_html/tools/smarty/sysplugins/smarty_internal_templatebase.php file, in line 281.

 

So I turned off smarty cache and everything works ok, no more blank screens.

 

I copied the file from instalation folder, same problem. Does anyone know how to fix this Smarty Cache tool?

I think I'm going through the same situation but my case is slight different. The front office is quiet good and no problem but in backoffice while updating the products it gives a errors or blank page or internal server error.

Modify config/settings.inc.php and set _PS_CACHE_ENABLED_ to 0 in order to disable memcached.

Does anyone know if this issue has been resolved in the more recent versions of Prestashop? This was my issue a couple of years ago. I am thinking of trying Prestashop again, but I don't want to go through the same exact mess. I do not need and cannot afford a dedicated server, so if that is the only thing that will cure this I may as well find a different shop setup.

 

What I am looking for is someone who runs Prestashop with no problems on something other than a dedicated server, and hopefully Godaddy because I have had so many failures with other hosts.

 

Please advise.

Similar error here   /home/      /public_html/classes/cache/CacheMemcache.php on line 156

 

 

I disabled memcache to file system cache and cleared the cache  (top right corner of the Advanced parameters - performance poge in presta 1.6.0.9 

 

stopped all blank white screens and and i could update products and save correctly after that.
