Fatal error

upgraded 4.7 > 4.8.4
PHP 8.0

what this error means?

Fatal error: Uncaught TypeError: set_error_handler(): Argument #1 ($callback) must be a valid callback or null, function "adminErrorHandler" not found or invalid function name in /www/apache/domains/www.sakulava.ee/htdocs/textpattern/index.php:69 Stack trace: #0 /www/apache/domains/www.sakulava.ee/htdocs/textpattern/index.php(69): set_error_handler('adminErrorHandl...', 32767) #1 {main} thrown in /www/apache/domains/www.sakulava.ee/htdocs/textpattern/index.php on line 69

Re: Fatal error

Can you check what plugins you have installed on that site?

And if you are able to set PHP back to 7.4 or 7.3 do you see the same error?

Re: Fatal error

There were some PHP 8 issues that slipped through the net in 4.8.4. This might be one of them. Could you download the current 4.8.5 branch and try that? We’re only a day or two away from release, with luck, so it’s production ready.

Call to undefined function Textpattern\Admin\pluggable_ui()

That is the strange part. It’s as if the Theme is trying to find that function (which is actually in txplib_admin.php now – it used to be in txplb_misc.php) in the Admin/Theme class instead of looking for it as a global function.

I know you’ve said you’ve updated the files a few times but here goes anyway:

  • Have you definitely updated textpattern/index.php to the latest version that came with 4.8.4 and ensured it’s not cached somehow?
  • Does lib/txplib_admin.php exist and is readable?
  • What Admin Theme are you using?
  • As jakob says, can you disable your plugins in the database by setting the status flags to ‘0’ and try again. If that works, switch them on one by one and see which one breaks it.

not sure it’s cached or not… i’m using FileZilla for files upload

  • Does lib/txplib_admin.php exist and is readable?

yes and readable (0644)

  • What Admin Theme are you using?

hive

will try this

meanwhile upgraded to 4.8.5

Re: Fatal error

Well that’s a different error than before so something has changed with whatever you just did.

All these “call to undefined function” issues seem to be related to files that aren’t up to date, or a plugin that’s failing because it’s trying to use functions that used to be in one file and have now moved. Are you using any front-end login plugins like mck_login or cbe_frontauth? The doAuth() function has never moved though, so I honestly can’t see it being that.

Maybe filezilla is not updating all files? Sometimes it does that if it thinks they’re not newer (e.g. a dstestamp issue).

yeah, looks like updating issue… disabled all plugins and… same error:

Re: Fatal error

went through all the files in /textpattern folder and they were all up-to-date. but folders ‘last modified’ date were wrong.

live page itself working well, but it doesn’t let me logon to admin side…

Try this:

  • rename /textpattern to /textpattern.old
  • upload new /textpattern directory, /index.php and css.php
  • copy /textpattern.old/config.php to /textpattern/config.php
  • make sure permissions are suitable for your hosting
  • try to log in
