hi,

I have the London template, with London version 1 installed with different J51 modules also.
After upgrading from Joomla 3 to Joomla 4, the whole website crashed, totally!

I just purchased the version 4 file of "London", but this has not been uploaded to the website yet..

So my questions:
1/ What is the best way to fix this ?
2/ Do I first have to restore a Joomla 3 backup, then upgrade the J51 LONDON theme, and then upgrade ?
3/ Do you have a step-by-step guide on how to best upgrade the LOND THEME AND MODULES and also from Joomla 3 to Joomla 4 ?
4/ What's the best way to keep all my theme settings and CSS modifications after upgrading ?

Thanks !

These are the errors I get:



Warning: require_once(public_html/components/com_content/helpers/route.php): failed to open stream: No such file or directory in public_html/modules/mod_j51layerslideshow/helper.php on line 14

Hello

If you have already updated your Joomla installation to Joomla 4 then you will need to install the Joomla 4 template and modules via your extensions manager. Once installed then your site should be back up and running assuming you have no other 3rd party extensions requiring an update.

If you find that your site loads but there is some error messages along side certains modules, then open that modules settings and save and close. This sholud resolve any errors.

hi Thanks !
That worked.

However, the contact page gives errors linked to the J51 London template. How can I fix this ?

Hello

May I suggest sending temporary administration access to your Joomla installation to info@joomla51.com and we will examine this issue further. For our reference please paste a link to this post in your email.
