Fatal Error

Hello @luskym

I am sorry about the issue you are experiencing and I am happy to help!
Can you please share the entire message to see the line of the code where the issue is?
Also, try to manually delete the cache folder, and go back to the W3TC dashboard, and save all settings and purge the cache.
Thanks!

Here is the full message:

Fatal error: Uncaught Error: Call to undefined function W3TC\wincache_ucache_get() in D:\Public\www\wp-content\plugins\w3-total-cache\Cache_Wincache.php:169 Stack trace: #0 D:\Public\www\wp-content\plugins\w3-total-cache\Cache_Wincache.php(146): W3TC\Cache_Wincache->_get_key_version() #1 D:\Public\www\wp-content\plugins\w3-total-cache\lib\Minify\Minify\Cache\W3TCDerived.php(123): W3TC\Cache_Wincache->flush() #2 D:\Public\www\wp-content\plugins\w3-total-cache\Minify_MinifiedFileRequestHandler.php(305): W3TCL\Minify\Minify_Cache_W3TCDerived->flush() #3 D:\Public\www\wp-content\plugins\w3-total-cache\CacheFlush_Locally.php(77): W3TC\Minify_MinifiedFileRequestHandler->flush() #4 D:\Public\www\wp-content\plugins\w3-total-cache\CacheFlush_Locally.php(87): W3TC\CacheFlush_Locally->minifycache_flush() #5 D:\Public\www\wp-includes\class-wp-hook.php(303): W3TC\CacheFlush_Locally->minifycache_flush_all() #6 D:\Public\www\wp-includes\class-wp-hook.php(327): WP_Hook->apply_filters() #7 D:\Public\www\wp-includes\plugin.php(470): WP_Hoo in D:\Public\www\wp-content\plugins\w3-total-cache\Cache_Wincache.php on line 169

Deleting the cache folder, saving settings, and purging cache still produced the above message.

Hello @luskym

Thank you for the information.
I assume that you are on the IIS server. Can you please share the website URL and can you also please share which caching methods you are using i.e. Disk or memory-based caching?
Thanks!

we have a couple of sites running off the same server and we also have test sites. Here is one of our production url’s – beatrooper.com. And we are using memory-based caching.

Hello @luskym

Thank you for the information.
Just a follow-up, Which caching method you are using from Page Cache and other modules?
Redis or Memcached?
more specifically, what is the Minify Cache Method: in Performance>General settings?
Thanks!

Hello Marko,

I work with @luskym and wanted to follow up with some of the additional information.

Our server team told us they have the WinCache Extension for PHP configured on the IIS Server. (https://www.iis.net/downloads/microsoft/wincache-extension)

The settings we have selected within the W3 TC plugin are;

Page Cache = Opcode: WinCache
Minify = Minify Cache Method: Opcode:WinCache

Please let us know if there is any additional information we can provide, thank you very much for your support!
