Drupal 7.x

I am preparing my computer to use one website on local. I have all ready, all works good, but when i put the name of the website on Google Chrome (all in local), appears this message:

Fatal error: Unsupported operand types in /xxxxxx/xxxxxxx/XXXXX/modules/field/field.info.class.inc on line 512

Error occurs during product import: An Importing Code error  An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /drupal/batch?id=56&op=do StatusText: Service unavailable (with message) ResponseText: PDOException: in drupal_write_record() (line 7247 of D:\XAMPP\htdocs\drupal\includes\common.inc). 

Whenever I try to do something (add a new module or something) I get the error (attached below). When I refresh the page it goes away.

I've cleared the cache and everything. I think it has something to do with languages as the Automat Language Strings Update Page doesn't work either.

Error:

Does anyone know of a repository of user-made content types, where I can browse, and ultimately import, content types other users have made? I realize many would be very specific to the original creator's needs, but I’m sure many would also be usable to other people. 

If if nothing else, it would give ideas on how to deal with specific challenges. Just trying to avoid too much "reinventing the wheel". 

Not sure why this condition is ALWAYS evaluating to true. Trying to check to see if the value in a long text field has been changed. 

The first field in the condition node-unchanged:field-security-audit is always evaluating as true. The second field node-unchanged:field-security-audit-status-pubf:tid is evaluating  properly. 

Any help would be greatly appreciated.

Here is the rule export: 

Hi, I started working on Drupal 7 for a few days for a project. I installed and worked with some modules, but I cannot get it to work like it needs to. I am trying to create a booking calendar. It needs to be able to send an entry to the desired date in the calendar. For example, I want to book a room from 8am-110am on feb 25 2017, it should come up on the calendar when I submit it.
