Exception #0 (ReflectionException): Class Ves\PageBuilder\Model\Config\Source\ElementList does not exist

Question

Magento 2.3.7, PHP 7.4.30

I installed the VES Page Builder extension (downloaded file from land of coder) manually, according to their readme:

Upload module files in the module packages in to folder: app/code/Ves/All, app/code/Ves/Setup, app/code/Ves/BaseWidget, app/code/Ves/PageBuilder

Then run commands

php bin/magento setup:upgrade --keep-generated
php bin/magento setup:static-content:deploy -f
php bin/magento cache:clean

It installed fine, but didn't work.

I wanted to get rid of the extension, deleted all files and performed:

php bin/magento setup:upgrade --keep-generated
php bin/magento setup:static-content:deploy -f
php bin/magento cache:clean

Now when I want to edit an existing product or create a new product, I get an exception:

1 exception(s):

What I tried:

I deleted:

www/m2/var/cache

www/m2/var/page-cache

www/m2/var/view_preprocessed/pub/static

I also tried:

php bin/magento cache:clean
php bin/magento cache:flush
php bin/magento setup:upgrade
php -d memory_limit=1G bin/magento setup:di:compile
php bin/magento indexer:reindex
php -d memory_limit=1G bin/magento setup:static-content:deploy -f

Any help is appreciated, thanks...

• Gork: Found it - there was an orphaned entry in the database: in table eav_attribute was an attribute with the source_model entry 'Ves\PageBuilder\Model\Config\Source\ElementList'. I deleted that attribute from the table and life is good again... :)

Answer 1

IN database search "ElementList" this keyword or whole path, and delete entry of this path from database.
