On a new and clean installation of OJS 188.8.131.52, any attempt to add a contributor results in the error “Failed Ajax request or invalid JSON returned.”. I tested it locally on MAMP for macOS before upload on my work server, and everything was fine there.
What ways can I localize where the error is?
OS platform - SunOS h1 5.11 184.108.40.206.5 i86pc
PHP version - 7.4.15
Apache version - Apache/2.4.46 (Unix) PHP/7.4.15 OpenSSL/1.0.2x
Database driver - mysql
Database server version - 5.7.32
P.S. In addition, I noticed that in the quickSubmit 1.0.6 plugin at the bottom of the form there are no radio buttons to select the type of article (published or not)
Attempts to enable
show_stacktrace = On and
display_errors = On do not cause an effect, result are not visible on the browser screen
P.S. And unfortunately, access to Apache or PHP logs for me as an ordinary user is prohibited by the administrator’s policy
