can't convert Symbol into String

Reported by Daniel Martin | September 21st, 2012 @ 02:57 PM

Looks like some sort of problem in:

RedCloth (4.2.9) lib/redcloth/formatters/base.rb:35:in `delete'

Adding debug traces to the function:

    def pba(opts)
      opts.delete(:style) if filter_styles
      opts.delete(:class) if filter_classes
      opts.delete(:id) if filter_ids

      atts = ''
Rails.logger.info "="*80
Rails.logger.info  opts
Rails.logger.info "~"*80
      opts[:"text-align"] = opts.delete(:align)

#...

This is what I get:

{:indent_before_start=>nil}

    This is the first time I have come across this website and here it discusses the details www.cbdcandy.com regarding some kind of programming issue. There is a problem in the code that we can't convert symbols into strings. How can we do that? I am looking for expert opinions from here. Keep up the good work.

    It is good that you have added the code that you have tried so that the people who know the programming can find out the issue with the code that you have shared and will definitely suggest a clear answer for it that helps in fixing the conversion of symbol into a string engagement rings bridal set
