I counted, and I can only have 89 pages in my menu. If I add a page number 90, it disappears when I press save menu. If I add a page called A as page number 90, and then switch place with another page called B (so the page B now is number 90), then it’s the page B that disappears when I press save menu. So all pages after page 89 gets deleted from the menu when I press save menu. That’s a bit frustrating.
Just to underline it, this is a new thing for me. I used to have like 140 pages in my menu. But when I tried adding some new pages two days ago, a big part og the menu just disappeared. I mean all the 50 or so pages that was after page number 89 just wasn’t in the menu anymore.
It’s a wordpress 3.9.1 bug. I’ve got the exact same problem. The similarity with your situation and mine is that I just updated WP, and now it fails. Request a bug-fix <del>or revert to a previous version</del>.
@esmi is right. I’ll look more deeply into it. I did deactivate all plugins, and reactivate all, but not individually.
or revert to a previous version
@codesmith32: That is very, very, bad advice! Such a site would be running a very real risk of being hacked. This is not a core WordPress bug but a site specific issue. It is also considered impolite to interrupt another poster’s ongoing thread unless you are posting a solution or suggestion. As per the Forum Welcome, please post your own topic.
@marteens: Have you tried:
– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).
– switching to the default theme to rule out any theme-specific problems.
– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.
– re-uploading all files & folders – except the wp-content folder and wp-config.php & root .htaccess files – from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.
After researching, I discovered the root of the issue.
The PHP 5.3.9 update includes a new php.ini setting called max_input_vars. This new setting is a restriction on the number of data values that may be sent back to the server, and was added as an attempt to potentially avoid some dos attacks. However, due to the fact that saving a WordPress menu sends back a large number of values (multiple for each menu item, especially when using UberMenu), the values will be truncated to this limit. The default value for max_input_vars is 1000, and if the PHP server being used has not adjusted this value, the maximum number of menu items that may be added successfully (with the UberMenu) is something around 80. Any more will not only be cut off, but the set locations (under Manage Locations) may also be lost.
Here’s a detailed report
Bottom line is, if you don’t have access to the php.ini file (which you typically won’t), you’ll have to contact your host to get the value changed.
Hi guys! Thanks you for answering.
@codesmith32, I did as you said and it worked 🙂 I contacted my host, and they made a php.ini file that I can change myself. Then I put max_input_vars = 3000 in that file, and now I can have more pages 🙂
So thanks again! 🙂
