Thanks for help.

I have a custom module which retrieves data from a third-party site (Strava). I have implemented a custom block via hook_block_view() which handles the authorisation dialogue between my user and Strava. This works and retrieves information about the user which I store as a database record. Now I want the user to provide data for some additional fields for this record. I have implemented a form to collect this data. Once the authorisation dialogue is complete I present this form to the user. The form includes a hidden field which contains the key for  the database record.

If someone tries to log into my Drupal site (http://mysite/user/login) is there a way to get an email if the username or password is wrong and the login attempt fails?

Hello,

As a web developer, I'm relatively new to Drupal and recently encountered a situation with a client's Drupal 7 website. Upon migrating their site to my VPS server, I ensured that the PHP INI settings and PHP version matched those of the previous server.

Although the website appears to be functioning correctly, I encountered an unexpected error when attempting to access the backend dashboard after logging in as admin. The error message displayed is:

"The website encountered an unexpected error. Please try again later."

Hello, I've taken over the running of a Drupal 7-based site at https://www.comicartfestival.com. All was going fine until this week, when, suddenly, lines of "active context" code started displaying on pages, for example the homepage...

I've clearly edited something wrong behind the scenes, can anyone advise on how to hide this, please? Thank you in advance.
