Describe the issue or problem
The eLife Lens article viewer usually works fine, except for files that do not contain graphics (i.e., when the tag is missing). In these cases, an “Error during loading” is displayed in an infinite loop.
What application are you using?
OJS 3.4.0-8
Additional information
Otherwise, the XML files are ok. They pass PMC validation and are displayed in PMC. This should be only an OJS issue.
