Manage Post > Add New Post generate error

Hi

Mage 2.0.5 (fresh install)
magefan/module-blog-master (May 14th)
.htaccess > Developer mode

If I want to add a post and click the Add New Post button, I get the following error below.

Anyone could give a heads up as to where to start looking that'd be kind

Thanks, Charles

Same here.
It's the same for adding/editing post or adding a category.

@commcad can not replicate the issue on my end. Tested on Magento 2.0.5 with master branch and tag 2.1.0. Maybe you have more detailed error backtrace?

[commcad]

Thanks for trying to help, too kind.

I'll reinstall the module and get it to throw the same error on 2.05. I'll email you the trace at your website address instead of posting this long log list here.

Has something to do with 2.05 because I've tried on a dev M2.02 and it was working just perfectly

Dunno, had a bounce back from your email svr, possibly doesn't like my txt file - don't blame it.

Backend > Content > Blog > Posts > Add New Post (but like mihaai reported, does the same for categories, add or edit). Anyone knows where we should start looking to debug this?

Just a quick update:

Magefan/Blog only install using the Magento Marketplace on Magento 2.05. Forget the $ php bin/magento command lines... well, that didn't work for me anyway.

1. Go to the https://marketplace.magento.com/, search for Magefan Blog, add to cart/checkout
2. In Magento 2.05> Backend > System > Web Setup Wizard > Component Manager
3. Sync
4. Install the module using Component Manager (Readiness tool > Backup >Next > Next, blah blah)

Works fine. Awesome module/tool. Donation on the way!
Unless mihaai has another problem and needs this to remain open, I have no problem this being closed

THANKS Magefan
