Fatal error: [] operator not supported for strings in /home/mysite/public_html/includes/common.inc on line 2445 [#2154685]

ubercart 7.3.5
drupal 7.24

This problem was discovered after a recent upgrade.
I have a product with a number of attributes. If the attribute is only text there is no problem.
However, if the attribute involves a "price" then I get the following error message:

Fatal error: [] operator not supported for strings in /home/mysite/public_html/includes/common.inc on line 2445

What versions did you upgrade from?
Why do you think that message is caused by Ubercart?
Was this a one-time message or do you always see it? What do you have to do / what page do you have to visit / what actions do you have to take to see the message?
What do you mean "the attribute involves a price"
Are you using any contributed ubercart modules? Which ones?

I upgraded to Drupal 7.24 Ubercart 3.5 remained the same.

This occurred after the Drupal upgrade. I just noticed it when I view a product with an option which has a price.

This occurs any time I try to view a product which has an attribute option with a price value entered. Text attribute options are OK.

For example, I have a shirt product for $20, option 1: color:red, blue, green etc. Option 2: xlarge: $5
One shirt with a color option of red displays fine.
One shirt with an xlarge option of $5 generates the error message.

I think it's doubtful that this is a problem with Ubercart core, because no one else has reported it and we have extensive attribute test cases. It's most likely a problem with one of those contributed modules.

I would start by disabling your contributed module - perhaps Variable Price first, because that affects prices ... See if you can reproduce this with just Ubercart core.

Solved!

the module readmorecontrol 7.x-1.1-rc2 was causing a conflict. Updating to the dev version solved the error.
Thanks for pointing me in the right direction - disabling modules one at a time.
