"Failed Ajax request or invalid JSON returned" after upgrade to OJS 3.3.0-22

[th_henkel]

Describe the issue or problem
After upgrading form OJS 3.3.0-21 to 3.3.0-22 a “Failed Ajax request or invalid JSON returned” error is thrown after clicking on “Read Review”

Steps I took leading up to the issue

1. Go to a submission in the review state
2. Click on ‘Read Review’

What application are you using?
For example, OJS 3.3.0-22

Additional information
The request is addressed to /$$$call$$$/grid/users/reviewer/reviewer-grid/read-review

The answer is in HTML:

Additional Information:
In the template file templates/reviewer/review/reviewerRecommendations.tpl the values of all elements of the array $reviewerRecommendationOptions are empty whereas the array was filled correctly in lib/pkp/classes/controllers/grid/users/reviewer/PKPReviewerGridHandler.inc.php

Could it be a translation issue?

Thanks for any suggestion.

Hi @th_henkel,

Check your PHP error log for details; it’s likely that there is a fatal error message that contains more information.

Hi Alec,

thank you for the hint. There was a conflict with an already declared smarty function in the cache. Clearing the the Template Cache solved the problem.

Best regards
