Just to clarify, "ARI Data Tables" v. 1.16.4 and "ARI Smart Content" 2.3.1 are compatible with Joomla! 3.9

This could not have happened at a worse time.

Error is: Fatal error: Cannot make static method Joomla\CMS\Helper\ModuleHelper::getModuleById() non static in class AriModuleHelper in /var/www/html/<mysite>/public_html/plugins/content/aridatatables/aridatatables/kernel/Module/j16/class.ModuleHelper.php on line 0

I have a critical US election-related website that cannot go down right now. Completely dependent on this extension and I have completely lost access to my back end (white screen) after J3.9 update, though the front end data queries continue to work thank god. ADT version 1.11.0 according to the XML file (I can no longer manage extensions from Joomla).

Can the 1.16.4 update be applied non-destructively? Our AriData Table setup is complex and we cannot afford to lose configurations.

We are not 100% confident of our recent pre J3.9 backup.

Please advise on best way to recover, and not loose any configuration.

Assuming updating the extension is completely non-destructive to configuration, how can I do that with no access to the Joomla back end update function?

Is there a way in the database extensions table to disable aridatatables so I can install your update fix?

Hello,

The extension can be disabled if login by FTP and rename <joomla_directory>/modules/mod_aridatatables and <joomla_directory>/plugins/content/aridatatables folders. For example rename them to _mod_aridatatables and _aridatatables. After this it will be possible to open the site and login to backend and update the extension.

Other solution is download here class.ModuleHelper.php file, login by FTP and copy the file to <joomla_directory>/modules/mod_aridatatables/includes/kernel/Module/j16 and <joomla_directory>/plugins/content/aridatatables/aridatatables/kernel/Module/j16 folders.

Figured out how to disable the plugin by setting Content - ARI Data Tables: enabled to 0

Got back into the J3.9 backend. Interface works.

Attempted to install 1.16.4

Install failed:

Warning
Joomla\Filesystem\File::delete: Failed deleting inaccessible file index.html
Package Install: There was an error installing an extension: plg_system_ariajaxdispatcher.zip

Changes the plugin folders permissioms recursivly to 777. Installed again, and got the same failure.

What next?

Am trying to replace the two files as you suggest with the one you just made available for download. Thanks.
