Custom Admin URL causes 404. How can I get back in to admin?

[erinBA]

I set a custom Admin URL in System Config & then saved the config. I was immediately kicked out to a 404 Page not found, and now I cannot get back into by backend. I tried the URL value that I set, as well as the previous versions that worked before ({MY_SITE}/index.php/admin & {MY_SITE}/admin). How can I get back into the admin panel? 

Thank you in advance for any help!

Hello,

It is not recommended to use the web interface to change your admin URL after the initial install.

Try the following.

Visit your local.XML which will be in app/etc

Find:
<admin>
<routers>
<adminhtml>
<args>
<frontName><![CDATA[admin]]></frontName>
</args>
</adminhtml>
</routers>
</admin>
The [admin] section will be your URL.

Update this, refresh your browser cache. See if it works.

If you have access to the DB, the following should undo the changes assuming no custom URL was set before:

UPDATE `core_config_data`
SET `value` = 0
WHERE `path` = "admin/url/use_custom"
LIMIT 1;

DELETE FROM `core_config_data`
WHERE `path` = "admin/url/custom";

 Disclaimer: no warranty implied, always back up your DB, etc.

Thank you for your quick reply, Conor Tomkins. Unfortunately that did not work though.

Thank you, Ben Marks!! That worked!

Also, I tried Conor's suggestion above and that DID end up working after refreshing Magento's Page Cache (in adition to browser cache). Thank you so much!

I tried both items and still cannot get back in.

Is there a way to flush the magento cache from shell other than wiping the cache dir?

update: I found the issue, apparently web/secure/base_url and web/unsecure/base_url also had gotten updated when

setting the new admin url. I removed the custom url off the end and it worked ok. (changed in core_config_data in mysql db)

If you're using memcache, make sure to purge the cache by restarting the memcache daemon or telneting into the host ip and issuing the flush_all command. If using file cache, delete the var/cache files. It all depends on the cache method you selected in your local.xml.
