Hello,
I'm sorry for your trouble.
You can find the update installation for Joomla 3 with Visforms to Joomla 4 with Visforms here:
[url]
vi-solutions.de/en/documentations/visfor...visforms-to-joomla-4
[/url]
It is not necessary to disable anything of Visforms before the Joomla update.
But it is necessary (quote): 'Before the Joomla update, you must have installed at least the Visforms Base Package Version 3.0.0 and the Visforms Subscription Version 3.5.5'.
Did you make sure, that the proper Visforms and Visforms Subscription version was installed before the Joomla update?
If not, you have to go back und make sure the proper Visforms and Visforms Subscription versions are installed before the update.
Did you enable all of Visforms after the Joomla Update?
If not, please enable all of Visforms which you have disabled before the Joomla upade and try again to update Visforms manually.
Regards,
Aicha
