PHP warning messages when updating

[kebekus]

Thank you for this wonderful plugin.

A while ago I started to see error messages whenever I try to check for updates. More precisely, the command 'wp plugin update --all' returns the following:

PHP Warning: array_merge(): Argument #1 is not an array in /var/www/html/wp-content/plugins/simple-mathjax/simple-mathjax.php on line 29

Thanks for the report.

@christianp do you have time to take a look?

[christianp]

I've rearranged the code so that everything is under a SimpleMathJax namespace. Can you pull the latest version from GitHub and let me know if that's any better?

[kebekus]

Hi, thanks for your very quick response. I puller version 2a5aa9e from GitHub a few minutes ago, and

• The plugin still works
• The issue is gone.
  Thanks again!

[christianp]

Fab! You caught me at the right time.

[pkra]

Thanks @christianp!

I need this fix as well. Is it expected that I am not getting this in the most up-to-date version of the simple-mathjax plugin found via wp-cli? wp-cli is telling me that I have version 2.0 and no update is available. Do I have to pull it via git for the time being?

[pkra]

Hm. Looks like the plugin registry is still at 2.0.

ping @christianp @scoskey do you happen to have access to the Wordpress SVN to push a release? I'm unable to get on at the moment.

[christianp]

I had changed the Stable tag field in readme.txt as the wordpress docs said, but it seems that I actually needed to change the Version line in simple-mathjax.php.

The wordpress.org plugin page now says that the current version is 2.0.1, so hopefully that has sorted it. @toddpfaff can you tell me if you get the right version now?

[toddpfaff]

I'm not seeing a change yet in wp-cli output.
