JPresta Cache Warmer
Can I get my invoice for the Cache-warmer service?
You can find your invoice in your JPresta account in the "Order history and details" menu.
If you don't see it make sure you registered an address in your account so the invoice can be generated.
Cache-warmer returns the error "Read timed out"
Unable to get cache-warmer informations from the shop (maybe the module is disabled or uninstalled): Read timed out
If you see this error in the log of the cache-wamer, that means there is a timeout when the cache-warmer retrieves the pages to warm up. To avoid this timeout, in the configuration of Page Cache Ultimate, click on "Advanced mode", then in the menu on "Options" and set a lower value for "Max execution time in seconds".
