OJS3.0.0+PHP7.1, article and PDF links give blank pages

Software Support

Hi:
Hosting service forces me to PHP7.1 or PHP7.2 so I upgraded from OJS2.x to OJS3.0.0.
I use driver = mysqli, otherwise it seems I’m toast.
On 7.1 I can access volume/issue pages, but article and PDF links give me blank pages.
On 7.2 I get all blank pages.
PHP5.6 works fully, but as said, I need to move to 7.1 or 7.2.
I tried the latest OJS3 instead and it gives me other errors.
I have essentially no capacities with any of this. Can anyone troubleshoot?

Thanks so much.

Hi @MENSTUDIES

The best way is to stick with OJS latest stable release.
Regarding OJS 3.0.0, do you see any relevant errors in the PHP error log?

Thanks. I have no idea where to look but I get:

PHP Warning: Cannot use a scalar value as an array in /home/public/sites/MYSITE/OJS/lib/pkp/classes/core/DataObject.inc.php on line 133

What errors do you see in that log right after you click on problematic galley links? Relevant are errors and fatal errors.

I get
PHP Fatal error: Call to a member function getRemoteURL() on null in /home/public/sites/www.MYSITE/OJS/pages/article/ArticleHandler.inc.php on line 230

apart from plugin warnings:
RelatedItemsBlockPlugin.inc.php
InformationBlockPlugin.inc.php
WebFeedBlockPlugin.inc.php

Hmm, I don’t see how this error can be related to PHP version. This error suggests that galley cannot be retrieved for this request. Are you sure that update was successful?

As I see, galleys can be retrieved by 2 methods, pub it or, if failing, by galley id. Can you confirm that inside submission_galleys table the information about the galley you are trying to access is present?

You can find submission id and galley id by URL, e.g.: http://domain.com/index.php/psp/article/view/127/269 where 127 - submission_id and 269 - galley_id

Thanks; sadly I do not know where to look. Again, PHP5.6 doesnt give me troubles. A more verbose error message on PHP7.1 is:
