Getting PHP errors – Just installed latest version

[dmccan]

Hi, I’m working on a development localhost site. I just updated the theme to 1.3.45 and the plugin to 1.2.95. I got a bunch of PHP errors when I saved a post. I disabled all plugins and switched to the 2012 theme and there were no errors when I save a post. I enabled only the GeneratePress theme (no plugins) and I get the error. I spun up a new blank site and installed the generatepress theme and get the error when I save a post, but not when using the 2017 theme.

Thank you for any suggestions.

I suppose I should say I’m using PHP 7.0.3 and WordPress 4.7.3.

Hi David,

Thanks for reporting this! A user capability check was added when saving meta boxes for security purposes, however the post ID was omitted from the function which can cause these warnings.

I’ve made the change and will push out an update after waiting a few hours to see if anything else pops up.

For now, you can turn off WP_DEBUG on your WP installation to avoid the warnings: https://codex.wordpress.org/WP_DEBUG

Glad to hear that you find the problem. In case it helps, I reverted to the previous version of the theme and with the plugin disabled there was no error, but with the plugin enabled I got an error. In other words, I was able to produce an error with the previous version of the theme and new version or the plugin AND with just the new version of the theme. I know they work together, just mentioning it in case it is useful info.

[Tom]

Yep, it’s due to the capability check which was added for extra security in both versions.

I’ll see if anything else pops up within the next few hours and will release updates with the fix 🙂

Here’s a fix if you need it before 1.3.46 is released: https://generatepress.com/forums/topic/1-3-45-notice-undefined-offset/

It would be great if you could confirm that it clears up the issue 🙂

Thanks!

Hi Tom,

I installed the plugin version 1.2.96 and the theme version 1.3.46-beta and was able to save a post with debugging on and got no errors.

Regards,

David

[Tom]

Perfect, thanks for letting me know!

I updated to the latest theme and plugin around 12 PST. Broke my Main Menu in the header. There was no padding between the nav links. They looked all clumped up. I restored to yesterday’s backup. I currently updated the plugin to the latest version but not the theme.

It’s likely that you’re removing query strings from your files. You probably just need to clear your browser cache once you update and you’ll be good to go.

Yup Fixed it. Thanks.
