i have Jason Template 1.0.1.
I want to use a version PHP > at 7.3 so i need to update my template.
Can you help me?
May i know what issue you are facing when you are upgrading the PHP version of site?
Any error on the template pages?
If i update the PHP at the 7.4 version i have "The parameter platforminfo.class must be defined." error...
Your site has outdated version of template and T3 kindly update them first
Can you help me to update T3 ????
Here are the updates steps : https://www.joomlart.com/update-steps
or you can download and install the latest updates via Joomla installer.
I have the 2.5.2 T3 Framework version.
Now, whats i download from the download page?
Kindly download latest version 3.0.8 and install.
Take backup of site before upgrade, Upgrade will override the core files if you have any custom changes.
also update template to latest version
I updated T3 framework.
Now i update the template.
I download the file of 2.0.1 version and i overwrite the old files by FTP.
Is it correct?
No it is not correct. Kindly use the method I shared via JA Extension manager or install it as any Joomla extension. Via Joomla backend > extension > install.
