Hi Paul

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.

Hi Ciaran,

The site is currently on my laptop, but I will put together a test in the next day our so online and if it is the same I will post a link and give you admin access.

Thanks,
Paul

Further update -

For some reason, the Thumbs Gallery has started working as expected on the laptop install (Joomla 4.0.3 plus latest version of module, PHP 7.4), BUT

online (also Joomla 4.0.3, PHP 7.4 and latest version of module) I get the error - Class'Joomla\CMS\filesystem\folder' not found

This is happening ONLY when I try to select the J51_ThumbsGallery.

Definitely confused! Joomla dashboard shows no errors!

Thanks,
Paul

Hi Paul

If you try re-installing the module via your Extensions Manager, does this resolve the issue? Ensure you are installing the Joomla 4 of the module.

Ciaran

Hi Ciaran,

I tried that - using the module that came with the updated version of the J4 Nina template. I deleted the original version before I did that too!

Strange I know,
Paul

Hi Ciaran,

This is quite strange - the error only happens with this module, although I don't have the same issue with the J4 install on my laptop.

I have re-installed the module and also re-installed the core files for Joomla 4.0.3 via the update option. I still have the same issue.

If you want to take a look at this the temporary admin user details are below. URL is also included. You can't break anything as this is a bare install
without any content as yet, except a media folder with six images that could be used to test the Thumbs Gallery module.

I know others have had a similar issue, perhaps this can help solve it.

Thank you Paul

That is certainly strange as it is an issue we are unable to replicate locally. May I suggest sending temporary administration access to your Extensions Manager (super admin) to info@joomla51.com and we will examine this issue further. For our reference please paste a link to this post in your email.

Ciaran

Thank you Paul

May I ask does the following file exist in your Joomla installation?....

../libraries/src/Filesystem/Folder.php

If not could you try adding it (attached - unzip first)

Ciaran

Hi Ciaran,

Just checked and folder.php is present, so still a mystery!

Paul

Joomla 4.0.4
Nina 1.0.3

Any news for this Problem?
I have the same with Joomla. 4.0.4 and Nina 1.0.3

this file is present in my installation
/libraries/src/Filesystem/Folder.php
the same Problem with joomla 4.0.4 and Nina 1.0.3

Hello

A bit of a shot in the dark this but the attached update resolve hopefully the issue.

Ciaran

If you are getting the Class'Joomla\CMS\filesystem\folder' not found error, try the following update instead.

Ciaran

It works in my installation. Thank you.
Testet just with one Picture

!!! Sorry, I was too quick, same error as before. !!!

Thanks Ciaran

I will give it a go once I am back at my desk .... seems like it ought to work though.

Paul

In my installation i see a version Nr 1.1 from Feb 2012. Is this OK?

Yes this is correct. The 2012 is the date the original module was released.

Ciaran

so, with the 2. download i can install Thumbsgallery but i get the following message.
