Having trouble loading up alternative themes, seems Journey crashes when a i select a new theme and reload the service, tried odin and casper themes.

Any idea what may be causing this?

[tooolbox]

This is caused by improper parsing of the templates. The "parsing engine" that finds the helper functions cannot handle delimiters inside of delimiters. For example, in the Casper theme there is:

{{!-- jQuery needs to come before``{{ghost_foot}}``so that jQuery can be used in code injection --}}

The findHelper function chokes on this, I believe because it mixes up the locations of the delimiters and winds up pairing them backwards or something. I get a panic: runtime error: slice bounds out of range, because the function tries to extract a block of bytes between indexes 1100->900...backwards.

A temporary workaround involves modifying those unescaped delimiters so they no longer match, such as making the above into { {ghost_foot} } (spaces added). I can confirm that this works.
