WordPress: plugins don't load (only) on homepage after update

Question

Hi there,

After several plugins got updated yesterday I saw in the source code that actually no plugin is loaded(1) on the frontpage anymore. On all the other pages everything works just fine.

The most obvious one is the menubar (wp-menubar-plugin), and for now I made an exception for the homepage(2) loading a hard coded copy of the menu as I couldn't debug the issue.

For comparison:

• homepage: as newby I only can post on link so please use the one below and click on "home" to compare the source code (only header) of the homepage and and all other pages. Sorry and Thank you ;)
• other page example: http://www.ehpress.com/specials/

I tried some debugging by deactivating all plugins and activating one after the other with no change. I had a look through all my template files and couldn't find anything that could cause this 'exception'.

Has anyone experience with this or a similar behaviour? I would be thankful for any hint where I could start with the debugging.

Thank you for any help, Albert

(1) the easiest test is the 'All in One SEO Pack' which should be found in the header

(2) if (is_page('home')) ... echo css and in the body echo html

Answer 1

I took a look at the source code of both the page you linked to and the home page. You're correct, there is no All in One SEO Pack entry in the source ... but there are other plug-ins that are placing code.

Namely, your home page is loading:

• WP FancyBox
• Menubar

You can see the stylesheet (CSS) and javascript entries for both of these plug-ins in the header.

Since you called out the All in One SEO Pack specifically, it brings to mind one possible reason this is happening - some plug-in updates aren't 100% automatic. If an author changes anything about the way he or she built the plug-in, they'll require action from the user (you) to update saved settings and database tables. The All In One SEO Pack does this from time to time, and it can be confusing if you miss the note.

Most of the time, a plug-in requiring a manual update will display a notice along the lines of Plug-in X needs your attention, please go to the settings page...

So I would recommend you go to the All in One SEO Pack's settings page and look for a checkmark that says "Enable Plug-in" ... chances are good that it's not checked and that checking the box will fix your problem.

Hi there,

I can't exactly say what it was, but after the provider change some permissions so that I don't get the 550 error again all the plugins work again as well.

Thanks again for your help!
