If you're this kind of developer..
Then you seriously need to reconsider your coding standards and structure.

Good News: WordPress has decided to update its embedded jQuery version to the latest as of Version 5.0

Bad News: Decided to look up what else to expect with that update, find out the Gutenberg editor is on its way to replace the TinyMCE editor, and will be sweeping meta boxes away along with it...

Fuck this shit! We had bug on website when tinymce was showing broken tables and could not save them correctly. So, the first thing you think about is tinymce is fucked up and you have to either upgrade, downgrade or fix it fucking yourself. Well, I spend more than hour tryingto figure this out. Then I found out that some fucker set column length in DB where data are stored to varchar 800!!! WTF, are you fucking serious?

Partially-inherited a WordPress website today that 1) has a ton of outdated plugins (therefore causing Visual Composer to complain), 2 was upgraded to WordPress 5 without keeping the old TinyMCE editor around, and 3) uses a page builder that's built into the "page options" portion of the Edit view.

We also have to add a couple of pages with the project in this state.

(For those not familiar with WordPress, "Page Options" can't be previewed before the page is published/updated, even though anything inside of the actual content area can.)

We got some work to do. 😐
