217: Too many hints for linked file

The left curly bracket { is used together with the right curly bracket } to provide a hint. Hints are usually displayed as a little text box when a user's pointer hovers over a region on the webpage. A hint can be combined with some linked files, namely images linked with [i]-> or [j]-> and media files linked with [v]-> or [w]->. In your case it is either combined with a different file type for which hints are not supported or you have combined multiple hints with a linked file where only one is accepted.

Solution

Merging multiple hints into a single hint is an option in combination with the file types [i], [j], [v] and [w]. Here is an example:

[i]->eye.jpg->/anatomy/{A human eye. Klick to learn about its anatomy.}

Otherwise consider using other means to convey information to readers. Captions are supported for all file types. The caption in the next example reads I would literally not …

[h]->ancestry-tree.html
I would literally not be here without these people.
