I am trying to save instructions to authors for one of our journals. Saving fails because of one single character; a c caron (č). Replacing it with a regular lower case c lets me save, but I do not think the author in question would like me to replace a letter in his name.
I have tried using both “č” and “č” in the source. Both cause OJS to “hang” when clicking “Save”.
What could cause this?
