SMARTY CACHE breaking our paypal module and checkout

[71newyorker]

Hi Everyone,

 

We've had a nightmare two weeks, our paypal module broke a few weeks ago and we have since been trying to fix it. 

 

By broke i mean, customer would order, go to paypal, successfully complete paypal payment but would go back our website looking at a blank screem. ALSO, the customers order would NOT show in the back office > orders page.

per other post, I suggest not using mysql for smarty cache, rather file cache.

also when working with modules turn off file cache.

Thanks El Patron, i will give this a try in 48 hours, we're a bit scared to touch anything else right now lol so we decided we will just monitor and let the website, cache, everything just settle for a few days. 

 

''also when working with modules turn off file cache.''

 

Can you explain what you mean by this? When you say 'working with modules' do you mean e.g when we're editing module files? 

 

Also what do you mean 'turn off file cache'? Do you mean turn OFF the caching system at the very bottom of the page? (performance page)

 

As always you have been very helpful, we really appreciate all of your input

smarch cache =  use file  cache...not mysql cache...mysql cache is brand new and is not default, nor is the any 'found' documentation on using the mysql for smarty cache.  this is probably your overall issue.

 

down at the bottom, file cache...

 

this can lead to some very strange behaviors,  especially in back office when working with modules, here is free module

 that will tell you  when file  cache is enabled/disabled...disable when working in modules section, enable file cache when done working in module section.
