undefined errors hearde already sent

Change the following lines
admin-css-js.inc.php line 20:

if (isset($_GET["ws_plugin__qcache_menu_pages_css"])) /* Call inner function? */

admin-css-js.inc.php line 28:

if (isset($_GET["ws_plugin__qcache_menu_pages_js"])) /* Call inner function? */

menu-pages.inc.php line 278

if (isset($_GET["page"]) && preg_match ("/ws-plugin--qcache-/", $_GET["page"]))

menu-pages.inc.php line 304

if (isset($_GET["page"]) && preg_match ("/ws-plugin--qcache-/", $_GET["page"]))

Same sloppy mistake made for all errors.

//Edit:
Also,
Change line 27 in menu-pages.inc.php to:

$updated_all_options = false;
						if ($verified || (isset($_POST["ws_plugin__qcache_options_save"]) && ($nonce = $_POST["ws_plugin__qcache_options_save"]) && wp_verify_nonce ($nonce, "ws-plugin--qcache-options-save")))

Also:
includes/classes/advanced-cache.inc.php
Add the folowing before line 41’s foreach.

$uris = '';

And change line 50 of advanced-cache.php (gets generated in your wp-content when enabling the plugin) into

if (!QUICK_CACHE_ALLOW_BROWSER_CACHE && !isset($_GET["qcABC"]))

//Edit:
Change lines 182-184 of includes/classes/readmes.inc.php into

if (isset($readme[$path]) || file_exists ($path))
							{
								if (!isset($readme[$path])) /* If not already opened, we need open it up now. */

Change line 30 of includes/_xtnls/markdown/nc-markdown.inc.php into

$parser_class = 'NC_Markdown_Parser';

woaw…

thanks ??

that worth an update !

This are only errors that will be shown when all errors are shown. The default for production servers will hide these errors and you can just run the software.

I think I’ll just dump all bugs and their fixes here ??

The clear button in the admin bar doesn’t work because of a JS change in newer WP.

Open includes/classes/menu-pages.inc.php
Replace on line 242 the word ajaxurl with:

\''.admin_url('admin-ajax.php').'\'

But when that’s fixes, you still have an ‘undefined’ error in the ajax response.

includes/classes/purgin-routines.inc.php line 68.
Put the folowing on a new line before the foreach.

$error = '';

//Edit:
Hit another one in advanced-cache.php on line 85

else if (QUICK_CACHE_DONT_CACHE_QUERY_STRING_REQUESTS && strlen ($_SERVER["QUERY_STRING"]) && !isset($_GET["qcAC"]) && !(count ($_GET) === 1 && isset($_GET["qcABC"])))

Change includes/classes/clearin-routines.inc.php line 24 into:

$cache = glob (WP_CONTENT_DIR . "/cache/qc-c-*-" . md5 ($host_uri) . "-*"); /* Match md5_2. */
if(is_array($cache) && count($cache))
	$cache = $cache[0];

includes/classes/admin-notices.inc.php line 99:

if (!$page || "*" === $page || $pagenow === $page || (isset($_GET["page"]) && $_GET["page"] === $page))
