@riseuplabs is this still an issue for you with the latest version?

Hi i get this error when using the plugin ep_copypad. I have the latest ep lite. The plugin is using an ep lite object so I thought it belonged here than there.

I have located and fixed this issue in my fix_timeslider branch. I can submit a PR for just this or we can wait until the entire branch is merged.

See s1341@6b74b44#diff-5d2aa4336c4964b828a123e20e09b73cR1284 and s1341@6b74b44#diff-5d2aa4336c4964b828a123e20e09b73cR1502

@Gared could you please test this branch out to see if it resolves your issue and let us know?

[s1341]

I've created a separate PR for this (#2038) so you don't need to test on my (as yet) unstable timeslider branch.

[Gared]

@JohnMcLear Okay. Will try this tonight.

[JohnMcLear]

Ah whoops sorry @Gared wrong person :)
