Updated OJS to 3.3.0-14 and now Article Statistics and System Infomation pages now showing -- IntlDateFormatter

[egadsby]

Today we updated to 3.3.0.-14 most things went well but two areas of the site do not display:

Administration->Administrative Functions>System Information

And

Statistics->Articles

The PHP log shows the following:

The problem seems to be with IntlDateFormatter… which a little looking tells me has to do with rendering of dates. This worked in 3.3.0.-13, what has changed with 3.3.0.-14? Any suggestions on how to remedy this? Thanks in advance!

@asmecher Thanks for the information and the help!

In my case was able to get it working by using “sudo yum install php-intl” from the CLI; we are using RHEL 8.5.

Just wondering, why had we been able to run OJS without this until the upgrade? Thanks again!

Hi @egadsby,

The latest build of OJS fixed Replace strftime() as it's deprecate in PHP 8.1 · Issue #7624 · pkp/pkp-lib · GitHub to improve PHP8.1 compatibility, but at the cost of introducing the new requirement for the intl module for older versions of PHP.
