Citation Style Language plugin not working in OJS 3.1.1

Hi,
I installed the 3.1.1 version,

When I activated the “Citation Style Language” plugin, I can no more display the page containing the article (title, abstract, etc). When I deactivate it, everything works again.

I am getting error 500

Hi @rajesh,

Hi @rajesh,

Those warnings are cosmetic, but they’re probably hiding an error message further back in the log file. Look for something containing the word “Error”.

PHP Fatal error: Call to undefined function Symfony\Polyfill\Mbstring\iconv_substr() in /home/journalpharma/public_html/ojs/plugins/generic/citationStyleLanguage/lib/vendor/symfony/polyfill-mbstring/Mbstring.php on line 558

Error Solved. Now it is appearing – How to Cite:

But,

When I changed Citation format from ACS —> to ACM or others… It again - page is not opening

Hi @rajesh,

Is there anything in your PHP error log this time?
