Unexpected Deprecated Call post 4.2.3 alpha upgrade

[interglobalmedia]

Hi,

I have attached a screenshot of a deprecated call I think showed up after my development environment was upgraded to 4.2.3. Don't exactly know what this means. The site looks and works fine, but this showed up much earlier today. Thanks!

Best regards,

Maria Campbell

Hi @interglobalmedia, thanks for the report. Which theme are you using?

Hi Sergey,

I'm using underscores.me theme for development. Just so you know, during all this, I lost large amounts of code that were fine yesterday evening before I called it a night. Today, much of the code is no longer there. There is still some there, but bits and pieces are missing. Hope this helps.

Best regards,

Maria

The error message is quite clear:

Please include a sidebar.php template in your theme.

Does your theme include a sidebar.php?

[interglobalmedia]

Hi John,

Yes, I do have a sidebar. That came up with another theme, not this one. What I was pointing out to was the fatal error that came up and is above that and has nothing to do with the sidebar issue. The fatal error showed up after midnight very early this morning after the 4.2.3 alpha update. Hope this helps.

Best regards,

Maria
