Autoload Error Module 'WeltPixel_OwlCarouselSlider' has been already defined

[shane_jenkins1]

I have installed Magento 2.3.1 on A2 VPS hosting and running the Porto theme. Php version is 7.1.30 (cli) (built: Jun 3 2019 21:06:56).

I didn't realise that the theme had the Owl Carousel Slider installed already so I downloaded the version from Market place. 

After installing a module through the Extension Manager I get the following error message for both front end and back end pages.

Autoload error

Module 'WeltPixel_OwlCarouselSlider' from '/home/fsadmin/public_html/vendor/weltpixel/m2-weltpixel-owl-carousel-slider-theme' has been already defined in '/home/fsadmin/public_html/vendor/weltpixel/m2-weltpixel-owl-carousel-slider-theme-free'.

The Extension Manager did determine there was an error in the install

Error in Update! 
Please refer to documentation Doc link to perform manual rollback.

To attempt automatic rollback, please click the "Rollback" button.

(See console log below)

The Automatic rollback didnt work and I can't get the manual rollback to work either. The files are where you would expect but running

php bin/magento info:backups:list

Comes up empty, the only response is

Autoload error: Module 'WeltPixel_OwlCarouselSlider' from '/home/fsadmin/public_html/vendor/weltpixel/m2-weltpixel-owl-carousel-slider-theme' has been already defined in '/home/fsadmin/public_html/vendor/weltpixel/m2-weltpixel-owl-carousel-slider-theme-free'.

Now I can't access the Magento Dashboard.

And can't work out how to remove the second version of the slider

I contacted WeltPixel and they said the following

Try disabling the module first, and then running a setup:upgrade command. Afterwards, try removing it via composer again with the composer removecommand, as instructed in this article: https://support.weltpixel.com/hc/en-us/articles/115006483588-How-to-uninstall-and-remove-a-Magento-2...

If you're still experiencing issues after trying this, I would recommend consulting the official Magento documentation and forums for a solution. Please also note that, currently, our modules do not support composer installation, and the supported installation methods are via manual SSH installation and the GUI install (PRO version only). 

When I check the modules using the command suggested 

• php bin/magento module:status

The only response I get is

Autoload error: Module 'WeltPixel_OwlCarouselSlider' from '/home/fsadmin/public_html/vendor/weltpixel/m2-weltpixel-owl-carousel-slider-theme' has been already defined in '/home/fsadmin/public_html/vendor/weltpixel/m2-weltpixel-owl-carousel-slider-theme-free'.

Composer runs fine, but none of the magento commands seem to work.

I've dug deep looking for a solution for this but have come up empty. Would appreciate some help.

Hello,

I am having a similar issue but mine occurred when installing Weltpixel Google Tag Manager.  

When I check the modules using the command suggested 

• php bin/magento module:status

The only response I get is:

Autoload error

Module 'WeltPixel_Backend' from '/chroot/home/a0e7bc0c/3333/app/code/WeltPixel/Backend' has been already defined in '/chroot/home/a0e7bc0c/3333/vendor/weltpixel/m2-weltpixel-backend'.

Any help is appreciated!
