I was recently advised to reinstall both wordpress and my wordpress theme due to (i think) a still unresolved error with a slide manager, but on doing so, apppear to have lost access to the admin-wp page login and instead now have a blank page with just the following errors appearing:
Warning: array_merge() [function.array-merge]: Argument #2 is not an array in /home/myusername/public_html/wp-content/themes/Carta/engine/backend.php on line 51
Warning: Invalid argument supplied for foreach() in /home/myusername/public_html/wp-content/themes/Carta/engine/backend.php on line 65
Warning: Cannot modify header information - headers already sent by (output started at /home/myusername/public_html/wp-content/themes/Carta/engine/backend.php:51) in /home/myusername/public_html/wp-includes/pluggable.php on line 890
I had also installed a couple of plugins recently, which I thought might be the problem, but on disabling them via FTP this didn't make a difference. If anyone has any suggestions as to what these errors refer to and how I can resolve them, I'd be very grateful. I'm a total novice with all of this, so the more detailed your instructions, the better. Many thanks.
