Porto problem with execute app:config:import

[matiaslliea151]

Hello people,
I have a problem, I run these commands:
1 bin / magento config: import,
2 bin / magento setup: update
in the cloud environment. On the console, I see this error:

PHP Fatal error: Uncaught Error: Cannot unset string offsets in /app/app/code/Smartwave/Porto/Model/Config/Backend/Customcmstabs.php:60
Stack trace:
#0 /app/vendor/magento/module-config/Model/Config/Importer/SaveProcessor.php(106): Smartwave\Porto\Model\Config\Backend\Customcmstabs->beforeSave()

#4 /app/vendor/magento/framework/App/State.php(187): call_user_func_array(Object(Closure), Array)

Any ideas?
Thank you.

I had this same issue.  I manually removed the reference to product tabs from the app/etc/config.php file.

1. porto_settings/product/custom_csm_tabs

2. porto_settings/product/custom_attr_tabs
