call to undefined function create_function() in 3.10.1 Topic is solved

[wcorrearj]

After upgrading from PHP 7.3 to PHP 8.0.10 I can't access the joomla control panel which is in version 3.10.1
Error: call to undefined function create_function()

[toivo]

The error comes from a third party extension, possibly a plugin, because the PHP code of the Joomla 3.10.1 core does not include any calls to the function create_function().

Please download the Forum Post Assistant (FPA), follow the instruction from https://forumpostassistant.github.io/docs and post the results here so that our volunteer experts can review the configuration.

The function create_function() was deprecated in PHP 7.2 and removed in PHP 8.0.0.

The website has the latest version of the third party component JA Extension Manager, 2.7.1, but also a much older version, 2.5.3, which should be uninstalled.

Two instances of the component Image Effect CK exist, but both of them are one point release behind the latest version.

The module Sigplus 1.4.3 is more than four years old and unlikely to work properly in PHP 8.

The module Perfect Everything in Every Way 2.0.13 may be at least two years old. Is the website using this module? It was replaced by the paid extension Shack Toolbox, last updated in 2020.

The old plugins from Perfect Web may well be causing the issue with the deprecated function create_function().

Download the plugins folder from the web server using File Manager or FTP into your workstation and search for the string create_function from the source code by using a utility like GrepWin. That way it could be possible to identify the origin of the error and then disable that plugin by editing the database table _extensions in phpMyAdmin or a similar database utility.

Hi, thank you very much for your help.
I did all the procedures and even so I couldn't go up with PHP 8. By doing research (create_function) I was able to identify the problem in the plugin: CEGCore2 (ChronoForms). After removing this "CEGCore2" everything is back to normal with PHP 8.

Another way to identify issue is to enable debug system option on global configuration. That will display which file causes error.
