Can't access or manage categories after uninstalling SW megamenu

[digitall]

I've searched the forum (and the rest of the web as well) but can't find anyone else with a similar problem.

After uninstalling an extension and a theme (newsmartwave porto, including extension megamenu) I can no longer access my categories page in the backend.

All cache has been deleted, sites been re-indexed and I have also done a setup:static-content:deploy

None has had any effect so far, and I can't figure out what's gone wrong.

I am inserting the report from /var/report/ to this to see if anyone can figure what's wrong.

Hi @digitall

it seems that old DI auto-generated classes still exist. Please run following command in the console, it should do the job:

$ cd /mnt/persist/www/magento-odelay/magento2
$ rm -rf var/generation/*

Cheers,

BX

Hi @Benoit Xylo, and thanks for helping out! Tried that, but no effect, generation is now empty, here's the new report

@digitall, I didn't read the exception trace carefuly enough, my beg. This extension added some new category attribute and didn't remove it on uninstall. You have to find it and remove manually.

To find it you have to run following query in your database (in either console or phpMyAdmin):

SELECT attribute_id FROM eav_attribute
WHERE source_model = 'Smartwave\\Megamenu\\Model\\Attribute\\Width'
AND entity_type_id IN (SELECT entity_type_id FROM eav_entity_type WHERE entity_type_code = 'catalog_category');

once you get ID of this attribute, you can delete it with following query (or you can find it in in eav_attribute table and delete using GUI of your choice, eg. phpMyAdmin):

DELETE FROM eav_attribute WHERE attribute_id = ATTRIBUTE_ID_FROM_PREVIOUS_QUERY;

As always, I strongly recommend to backup your DB prior to direct operations on the database.

Cheers,

Big thanks for the quick response and the solution @Benoit Xylo! This solved the problem (i added three other entities in eav_attribute that had the Smartwave/megamenu path just to be sure)

[Benoit Xylo]

No problem, I am glad you could solve your issue. BTW such extensions should be blacklisted somewhere publicly, especially Magento 2 implemented (finally) uninstall scripts handling, so each module should clean up after itself on remove.

Cheers,

BX

[digitall]

Totally agree on that.

Thanks again :-D

[todd_robards]

Worked for me.. Cheers

Smartwave themes themselves should be blacklisted. 

They tried blackmailing me $4,000 for an integrators licence when I added 2 domains to my site and then they disabled my site theme from their end.

Thank you @Benoit Xylo it works.

Hi, can you tell more about the Porto theme issue? 

Is it true the developer and stop your theme remotely?

I encounter their bad support and the theme doesn't work well recently.

thank you.
