Like Grid, the shiny new first-party add-on? 😊
No, third-party.

Disabling Grid worked for me… allowed me to create a new field.
However, I ran into the error again when trying to create a new Low Variable.

Yup me too directly after upgrading to 2.7.3. EE—please any word on this… this issue was reported back on DEC 4th!

As asked in this reply http://ellislab.com/forums/viewreply/1058852/ do you still get the error when all other add-ons are disabled? So only stock add-ons with grid enabled.
Ellislab is saying that this is a conflict between grid and other add-ons that aren’t managing package paths correctly.
At least, that is my understanding.

Hmm, if I uninstall grid from fieldtypes and it removes any associated data—what would that do to my system? Am I going to lose any information? I don’t evne know what that grid fieldype does or is.

I have the same situation with you.

I just had to downgrade my installation of EE because this bug wasn’t being taken care of by EE at all. Hopefully it will in the near future.

Just a quick note- if you’re sure something is a bug, don’t hesitate to post it to the Bug tracker. In this case, it’s not a bug in EE- it looks like some addon is probably using add_package_path() to set the path (which they shouldn’t need to) and the not setting it back. So anything AFTER that- now has the wrong path and is looking in the wrong place if it needs to load a view or such.
In other words- you need to identify the third party add-on that’s breaking things and fix that.

Thanks Robin, seeing this post I grep’d all my third party add-ons and found that 8 are using add_package_path(). I haven’t tested if they set the path back or not, but as you say, they should not be using it in the first place?
Cartthrob
CT Admin
mithra62:EE_debug_toolbar
DevDemon_Forms
Solspace Addon Builder
Matrix
Playa
It would seem use of this is fairly widespread. Hope that changes soon.

...they should not be using it in the first place?
There are cases when you do need to call add_package_path(), but they need to make sure to balance it with remove_package_path() when they’re finished.

Thanks Kevin,
Carthrob and DevDemon in one of their classes uses remove_package_path(), the rest don’t appear to. Time to check for updates and contact authors I guess. Thanks for the update!

I have no third-party addons installed and I have the same situation. On both 2.7.0 and 2.10.1 though I’ve since replaced the 2.10.1 (dev) environment to try to fix without altering production.
I even disabled absolutely everything I could including all file types, modules, plugins, etc. (all were EE/first-party). Then I enabled Text Input field type only. Could create a new channel field. Enabled Grid and back to the problem.

Finding my issue is related to mod_security rules. Getting it sorted out now.
