Hi all,

So I backed up my RSFormpro! forms from joomla 3.x and restored them them in the joomla 4.x (test site). via the RSFormProl extension. However when I run the form in joomla 4.x (with debug on) I am getting errors like this.

Joomla\CMS\Factory::getLanguage() is deprecated. Load the language from the dependency injection container or via Joomla\CMS\Factory::getApplication()->getLanguage(). 16384

I know previously when going from joomla 3.x to joomla 4.x, I basically had to reinvent the wheel and reproduce stuff manually. Do you think I have to go from scratch and create a new form in joomla 4.x ?

Let me know what you think

Why don't you disable debug? Or switch it to more silent?

Hi,

I turned on debug to find out where the errors were with my RSFormPro form that I created. I did turn it off though. I probably am going to create a form from scratch and put all the setting in their from my previous forms that I upload into joomla 4.x from joomal 3.x.

@rambro Creating a new form won't help solving your issue. Better contact RSFormPro developer, ask them to check and solve the issue in their extension.

What I meant: You can configure debugging less noisy. If you use for example n3t Debug plugin you can switch off USER_DEPRECATED messages and others. You don't need then Joomla's debug configuration and "Error reporting". At the moment it is a waste of time to debug Joomla inclusive USER_DEPRECATED messages when you are not a developer. Even Joomla Core is throwing hundreds of these messages, e.g. in HTMLHelper. If an extension also wants to support 4.0, 4.1 by promise it is almost pointless.
