Hi @Dawit_Uta,

It looks like your PHP configuration is missing JSON support. You may need to add the JSON module to your PHP environment.

bcmath, bz2, Core, ctype,date, dom, filter, gd, hash, iconv, intl, json,libxml,mbstring

SPL,standard, sysvmsg,sysvsem,sysvshm,xml,xmlreader,xmlwriter,zip,zlib
[Zend Modules].

I think there is another issue.

Hi @Dawit_Uta,

Your command-line PHP configuration may be different from your web-based PHP configuration, and it may also be necessary to restart your web server after changing the configuration files, depending on your server API.

Hi @Dawit_Uta,

There should be a message in the PHP error log whenever you encounter a 500 error. But if you find it and need guidance, could you post that as a new topic? That’ll help keep the forum organized.
