Hi,

I made an update from Joomla 3.9  à 3.10, after having updates with precaution on extensions

And then I made a migration from Joomla 3.10 to 4.1

Before the migration I made a backup with Akeeba.

Unfortunalety the migration didn’t work very well so I made a restore with Akeeba to be back to Joomla 3.10

After the restore to 3.10, I have got problems on the back end and front end site

On the backend I have :

• No problems to display the configuration pannel, and most of the first pages of components
• But when I click on menu, article, module, etc… I have got these problems

It is displayed : Class 'JFormFieldList' not found

Or Class 'JFormFieldPredefinedList' not found

It seems like having a link with the forms

On the front end web site some pages are ok but other are not : I have got this kind of message (see the website here for example : https://www.udsp05.fr/udsp-05/udsp-05-statuts-et-reglements)

Can You help me ?

Thanks

Sandrine (I am french)

ps : I still have got a .jpa file made earlier in the day before updating to Joomla 3.10, i would like to avoid to use it because between the update of 3.10 and this backup I made a lot of work on the website

Here is a precision :

I can access to "extension - database"

and I Have problems in database found (see image)

or the button "correction" doesn't work and I can't correct it

Hello Nicholas

and thanks for you replying

I am ready to work on it

when you say "delete all the files and folders" : can I just move them on a folder at the root called for example

_save

in case ?

thanks

Sandrine

Hi Nicholas,

Everything if fine, thank you so much !

and I haven't lost any work done, perfect!!

I just have to do the same now with the other website

(but the problem is a little bit different, as I wasn't so meticulous in making the backups..

I let you know

Sandrine
