Problem accessing Admin after installing Simple SEO

I am getting the following error when trying to login to Admin:

Warning: main(includes/functions/html_output.php): failed to open stream: No such file or directory in /home/content/r/m/o/rmoffett/html/admin/includes/init_includes/init_general_funcs.php on line 33

Warning: main(includes/functions/html_output.php): failed to open stream: No such file or directory in /home/content/r/m/o/rmoffett/html/admin/includes/init_includes/init_general_funcs.php on line 33

Fatal error: main(): Failed opening required 'includes/functions/html_output.php' (include_path='.:/usr/local/lib/php') in /home/content/r/m/o/rmoffett/html/admin/includes/init_includes/init_general_funcs.php on line 33

How can I fix this?
Thanks.

The error message is telling you that you're missing the /admin/includes/functions/html_output.php file on your server.
Perhaps your FTP program failed to upload everything properly.

I resolved my previous issue, now I am getting the following error when I type in my website URL:

PHP Fatal error: Call to a member function on a non-object in /home/content/r/m/o/rmoffett/html/includes/languages/english/credit_cards.php on line 46

Any advice would be much appreciated.

Again, it seems like you may be missing files from your FTP upload.

Everything was working fine a few days ago, then I tried uploading Simple SEO software from Zen-Cart. That's when all my troubles began. I went through and deleted all the SEO files, but I am still having issues in areas that seem unrelated.

With regards to my latest issue, PHP Fatal error:
Call to a member function on a non-object in /home/content/r/m/o/rmoffett/html/includes/languages/english/credit_cards.php on line 46

I go to line 46 in the PHP file, which reads: define('IMAGE_CC_ENABLED_MC', zen_image($template->get_template_dir('cc2.gif', DIR_WS_TEMPLATE, $current_page_base,'images/icons'). '/' . 'cc2.gif'));

What do I need to do to remedy this?

1. Do you have a backup of everything from "before" you installed the addon? Backups make recovering from these kinds of things much easier.

2. Try re-uploading all the original versions of the /includes/auto_loaders/ and /includes/init_includes/ files, since the $template object is instantiated using those scripts. If you have extra files in those folders or their subfolders that weren't in the original Zen Cart files, remove them.

Of course, you should make backups even now before you go changing and deleting files.

Don't forget to also do database backups when you're doing backups of your PHP files. https://www.zen-cart.com/tutorials/index.php?article=103

Next time, post the issue in SSU support thread will give you more help

Also, it seems like you edited the wrong file. You were not supposed to edit any file in admin.

And SSU edits only 1 file: /includes/functions/html_output.php

No other core files should be edited or overwritten.

Make sure you use the latest version as well http://public.rubikintegration.com/
