Hi @nacho,
This warning:
Warning : Zend OPcache API is restricted by “restrict_api” configuration directive in /home/revistasmarcialpons/www/lib/pkp/classes/cache/FileCache.inc.php on line 59
…is caused by your server having disabled the opcache_invalidate function. I’m not 100% sure but I believe your system should work fine – it’s just a courtesy call to the opcode cache when one of the OJS caches needs flushing.
As for the second error:
Fatal error : Uncaught Error: Call to a member function getData() on null in /home/revistasmarcialpons/www/cache/t_compile/99c8119641c8b66505bcc40a18c71f8cd78c01e4^504348cc7222e1110a6019067f9a002726c02324_0.plugins-plugins-generic-pdfJsViewer-generic-pdfJsViewer.display.tpl.php:60
This looks to me like a data problem. Can you describe this submission in more detail? Was this a submisison created and/or published using a prior release of OJS, or did it start with OJS 3.2.0? That is to say, where in the submission’s publishing lifecycle did the upgrade happen?
