I turn on page cache (basic), first load is fine (i can see cache file being created on disk, but debug info shows: * ``` Cache key: w3tc_mydomain.com_1_page_05f935faf9590a8e30d6249707373a77_ssl Caching: enabled Status: not cached ``` * On second load I get 500 internal error, same goes for every page… * These are the .htaccess rules: * ``` # BEGIN W3TC Page Cache core RewriteEngine On RewriteBase / RewriteRule ^(.*\/)?w3tc_rewrite_test$ $1?w3tc_rewrite_test=1 [L] RewriteCond %{HTTP_USER_AGENT} (240x320|2\.0\ mmp|\bppc\b|alcatel|amoi|asus|au\-mic|audiovox|avantgo|benq|bird|blackberry|blazer|cdm|cellphone|danger|ddipocket|docomo|dopod|elaine/3\.0|ericsson|eudoraweb|fly|haier|hiptop|hp\.ipaq|htc|huawei|i\-mobile|iemobile|j\-phone|kddi|konka|kwc|kyocera/wx310k|lenovo|lg|lg/u990|lge\ vx|midp|midp\-2\.0|mmef20|mmp|mobilephone|mot\-v|motorola|netfront|newgen|newt|nintendo\ ds|nintendo\ wii|nitro|nokia|novarra|o2|openweb|opera\ mobi|opera\.mobi|palm|panasonic|pantech|pdxgw|pg|philips|phone|playstation\ portable|portalmmm|proxinet|psp|qtek|sagem|samsung|sanyo|sch|sec|sendo|sgh|sharp|sharp\-tq\-gx10|small|smartphone|softbank|sonyericsson|sph|symbian|symbian\ os|symbianos|toshiba|treo|ts21i\-10|up\.browser|up\.link|uts|vertu|vodafone|wap|willcome|windows\ ce|windows\.ce|winwap|xda|zte) [NC] RewriteRule .* - [E=W3TC_UA:_low] RewriteCond %{HTTPS} =on RewriteRule .* - [E=W3TC_SSL:_ssl] RewriteCond %{SERVER_PORT} =443 RewriteRule .* - [E=W3TC_SSL:_ssl] RewriteCond %{REQUEST_METHOD} !=POST RewriteCond %{QUERY_STRING} ="" RewriteCond %{HTTP_HOST} =mydomain.com RewriteCond %{REQUEST_URI} \/$ [OR] RewriteCond %{REQUEST_URI} (sitemap\.xml(\.gz)?)
