About Missing MyCode (BBCode) Editor Bug
Many MyBB users report their MyBB editor is missing due to various reasons which we’ll cover here.
Before we start, we need to be sure that the MyBB editor is actually enabled on your account and for the entire board.
To enable the MyCode editor for the entire board: Go to Admin CP -> Configuration -> Settings -> Clickable Smilies and BB Code -> Clickable MyCode Editor and tick ON
If the above setting is on but you still can’t see the MyCode editor but everyone else can, then you most likely don’t have it enabled through your User CP.
To enable it in your User CP, go to User CP -> Edit Options -> Other Options and tick “Show the MyCode formatting options on the posting pages.”
Now if you have both settings enabled and you still can’t see the MyCode editor, then you are most likely missing something. Below are some additional problems/solutions, ordered by most likely to cause or fix the issue, respectively.
CloudFlare

Theme Editor Style

If this solution works, then it means that there’s a problem with your editor theme files.

Fourth Solution (Template Issue)
Go to Admin CP -> Templates & Styles -> Templates -> <Your theme> -> New Thread Templates -> newthread and Admin CP -> Templates & Styles -> Templates -> <Your theme> -> New Reply Templates -> newreply.
Make sure you have {$codebuttons} right after <textarea id="message" name="message" rows="20" cols="70" tabindex="2" >{$message}</textarea> in newreply template and right after <textarea name="message" id="message" rows="20" cols="70" tabindex="2">{$message}</textarea> in newthread template.
Revert Templates
This solution is only valid if the editor went missing after you upgraded or downgraded your forum.
Find updated templates for your current theme and revert them to original.
Go to Admin CP -> Templates & Styles -> Templates -> Find Updated Templates
SQL Query to Force Re-Enable the Editor for All Users
If the codebuttons are showing for you and only few members are unable to see it, then you can run the following query to enable “Show the MyCode formatting options on the posting pages” for the whole board through this SQL query:
UPDATE `mybb_users` SET `showcodebuttons` = '1' WHERE `showcodebuttons` = '0'
** Note: Make sure you back up your database before running any SQL queries manually.**
** Make sure to change the mybb_ table prefix in the example to whatever your table prefix is.**
