I'm retrieving two values of the same transient, the actual transient value itself, along with its timeout value. The transient seems to have no expiry date. I compared the UNIX time differences between the expiry date of the transient and present time. W3 Total Cache seems to have cached the value for over 7 days ahead of its expiry period.
When I cleared all caches and disabled the plugin, the problem got resolved.
Is there any way this can be resolved without disabling the plugin? Perhaps I can temporarily disable the object cache temporarily until the next release?
