Drupal 7.x

I was working on some code in a node text area and after my last save it broke the site completely.  I now get a blank page with the generic error "The website encountered an unexpected error. Please try again later."  I cannot login.

I tried deleting the node and node type with PHPMyAdmin but it made no difference.  I need to know where the textarea data is saved so I can delete the code I input please.

I'm open to other suggestions too.  I'm running a very recent version of 7

Thanks for reading.

Hi!

I have two identical Drupal sites. One is installed at the root of the server and the other in a /testing folder. Each one has its own database but the data contained is the same.
Well, the drupal_mail function on the server root sends the emails but the /testing does not.
Why?  The emails are sent through SMTP Authentication and use Sendgrid's SMTP server.
Any idea why this happens?
Thank you

Hello,

Hi, firstly a huge apology as I am a new user trying to learn the ropes. I have a business which I have just taken over and it had a Drupal based website built a couple of years ago. I have been trying to learn the basics and fear I have made a bit of mess of things! In my attempt to stop spam incoming, I installed a captcha module (not uninstalled) and since then my clients have been unable to create a new used account, this obviously causes me some issues!! All I get is the following error when trying to create an account. 

I have this problem to update a view with the views module, when making a change it shows me on the screen a chain of characters similar to a query in the database, how can I solve it

I have inherited a Drupal platform with around 50 websites. They are all hosted on virtual machines that we have internally; and are all a part of the same Drupal 7 multisite setup. The convenience of multisite has been great for us since updates happen in one spot, and since ~40 of the ~50 sites are nearly identical in form and function.
