XF 2.1 503 error when installing import addon

[Jon12345]

The title says it all. Now, I have a message that says:

One or more add-ons currently have actions pending and may be in an inconsistent state. Because of this, some errors may be suppressed and unexpected behavior may occur. If this does not change shortly, please contact the add-on author for guidance.

This is a fresh installation of a xenforo, and I just tried to add the import addon.

Next to the addon is a label saying, "Action Pending."

Fixed now. My host raised the lsapi max connections to 200 and restarted LiteSpeed.
