We have an open bug report for this one 🙂 Thanks for reporting
 

In the system itself, emails are unique. So any custom developed SSO should do this anyway, and anything in built such as OAuth login, will ask the user to log in with their account if its detecting to already exist. After which the 2 will be linked

You would need to contact your hosting provider about the error there. "MySQL server has gone away" means the database is not responding to request from the software

But you know that from the front end

You can create your blocks in the admin CP, and create those with permissions as custom blocks. This way you can pick and choose which blocks show to which groups as neeeded

Have the background tasks within your admin CP completed? You can see these on the dashboard

Pages is an application in which you can create pages or databases of pages in. Those pages could be named anything you like, and the databases and records could also be named anything you like. 
When you are looking at articles, that is just a pages database which has been called articles. Databases contain records that can be given a name. In this case, articles. 
So you have articles, which are stored in a database also named articles, which are within the pages application on our software. Of course you can create any number of things with the pages application, rather that articles. In an example here, we have created a database named recipes
 
 

These are not something available in the default product at present. Version 5 however does indeed have heading items you can add.

If you just move their usergroup, then they have no subscription to 'nag' them to pay 🙂 

Ive created a ticket for you, so we can discuss your needs here
 

This guide uses an example of an ebook, but essentially does exactly what you are looking for here
 

Ive added the latter part there as a bug. It may well come back as needing to be a suggestion, but it may have simply been overlooked there.
In terms of the card and shipping there, its unlikely this will be changed. Simply as shipping doesnt exist in the next version, so that would not be an issue in the first place

Officially the software works with mysql. However as a drop in alternative, there are many users who use mariaDB

I've given Lindy a shout on this to see if he can take a look at your last message.

You dont have permissions on the front end. You need to check Members>Staff>Moderators, and ensure you have permissions for everything in there

I have created a ticket on this one for you

They would need to be in the same location, as they need to have access to the file system of the installation they are converting from

There is no setting which would do this at the present time. Feel free to post up within our feedback area if this is something you wish to see in the fuure. At present, once clicked, it is assumed you are happy to view NSFW content.

There should be a share icon at the top of each. Bear in mind this will only show if guests can view. Is this the case?

You have some disabled there. The 'standard' one its referring to is one of the ones that are disabled, that have it set up to sync emails. There is one present, whether disabled or otherwise. So you need to remove that or change it

Word filters work with post content only at the present time

If you go to Commerce>Payments>Settings>Email copies, you can set up there so you get a copy of any email a customer gets. So therefore you could set up there to get a copy of the email confirming payment 🙂 

In terms of status updates, its worth pointing out these are deprecated items which will not exist in version 5. So if you are starting a new site, its probably advisable not to enable those at all.
In terms of feeds, you can create feeds of these things using the block manager. Please take a look at the following guide on this
 

If you change a price, when you save it will ask you if you want to amend it for people who are already subscribed
Same as above. However in this case, as they will not be on their first month, nothing really changes for them

This should now be resolved
