Clean WordPress install for testing, and I just got the “The plugin does not have a valid header.”

I figured out what happened….

My cron job to fetch the latest versions for my mu-plugins from:

wget -O varnish-purge.zip https://downloads.www.ads-software.com/plugin/varnish-http-purge*.zip

After I examined the varnish-http-purge.php file, it’s actually 3.8-beta.

So I’m actually having problems with 3.8-Beta. The sites that are still using 3.7.3 doesn’t have any issues.

I was able to resolve the wp-cli issue, which is working. Instead I use:
wp –allow-root option update vhp_varnish_ip XX.XX.XX.XX \;

Success: Value passed for 'vhp_varnish_ip' option is unchanged.

However, with the varnish-http-purge.php (in mu-plugins), my websites are still displaying inside of a box. I have no idea how it would even effect the sites. If I remove the plugin, everything is displayed correctly again.

I fixed the problem by not turning on Force SSL admin on by default for new sites.

I currently use your plugin and love it, but I found a background slider that uses html5/css3 and I think would make your plugin awesome. Here’s a demo of it:

You can download the template and easily implement it with your plugin:

My humble apologies…. it wasn’t this plugin. Any plugin I put into the plugins folder will show that I have an update available even though I don’t.

I have no idea what is causing it.

Howdy Ross,

Thanks for the fast reply and the quick fix! That worked beautifully.

Hey Ed,

Can I just paste your code in code snippet and activate?

Interesting2me THANK YOU!

My WordPress Multisite admin is finally working. I was getting the same errors mentioned above by other people. Enabling/disabling plugins, themes, etc was all quirky. I also have apc.filters=”-(.*apc\.php)|(.*/wp-admin/.*\.php)” but that didn’t stop APC from caching the admin section.

If your apache httpd.conf has

Include conf.d/*.conf

you can just create a new apc.conf in conf.d:

<Directory "/path/to/wordpress/wp-admin">
 php_flag apc.cache_by_default Off
 </Directory>

Any plan to support 5.1.x? My control panel uses 5.1.69 and i dont think i can change it without breaking it. And does this support Multisite?

I had the same problem and after smashing my forehead against the keyboard for a few hours, I found out the culprit. In my case, if you are using the Domain Mapping, you have to have the domain option #4 enabled:

“Redirect administration pages to site’s original domain (remote login disabled if this redirect is disabled)”.

I don’t know why it doesn’t work without redirecting.
