something is creating script error

PLEASE HELP , its always happening from the beginning i play gmod (maybe after i installed some addons) can someone help? any help would be appreciated

Take a screenshot of your console when you get the errors so I can see what is causing errors.

You could also copy and paste everything in it.

Just having a script error is not enough information to help completely. However,you should be able to tell what addon is causing the problem. Open the console to see what the error actually is by pressing ` (the button just above your tab key on the left). Read the error. It will say "[ERROR] addons/[addon that is causing the error/rest of the file path. If this is singleplayer you will need to unsubscribe or disable that addon to get rid of the errors. If it is a server (with the addon extracted), you can try to fix the problem by following the path and edit the file that is listed in the error.
