White Screen of Death when saving menu and SmartCrawl is active

Hi,

I suddenly started getting white pages when saving a small change on a menu. I could still apply changes from the "Customise" view in Appearance, but there are some changes that are only possible in the Menu dashboard.

I activated the debug and noticed that the only errors were related to SmartCrawl. Deactivating the plugin I could save the menu again.

An extract of the errors:

    Hello Mirko
    Hope you are well today!

    Unfortunately, I could not replicate the same on my test site with Smartcrawl and the default Twenty Sixteen theme. I understand Deactivating Smartcrawl fixes this error, can you check to make sure you have the latest Smartcrawl version installed?
    https://premium.wpmudev.org/project/smartcrawl-wordpress-seo/

    If so, you should perform a full plugin/theme compatibility test.
    1. Deactivate all plugins but Smartcrawl.
    2. Check to see if the same happens.
    3. If not, start Activating your plugins one by one until you find the one causing this issue.
    4. If so, try switching your theme to the Twenty Sixteen default theme.

    Could you please also let me know which PHP version you are running on your server? You can find this under WPMU DEV > Support > SYSTEM INFO.

    Looking forward to your response.

    Cheers,
    Alex :smiley:
