Title: Fatal Error on plugins screen Last modified: September 30, 2025 --- # Fatal Error on plugins screen * Resolved [alexstandiford](https://wordpress.org/support/users/alexstandiford/) * (@alexstandiford) * [6 months, 2 weeks ago](https://wordpress.org/support/topic/fatal-error-on-plugins-screen-2/) * Hey there! We’re seeing a fatal error on the plugins screen, and it’s due to a dependency conflict between your plugin and another plugin using the same dependency. I previously discovered this [on the other plugin](https://wordpress.org/support/topic/fatal-error-on-plugins-screen/) * Here’s the error code: * `PHP Fatal error: Declaration of Symfony\\Component\\Cache\\CacheItem::expiresAt(? DateTimeInterface $expiration): static must be compatible with Psr\\Cache\\CacheItemInterface:: expiresAt($expiration) in /wp-content/plugins/integration-cds/vendor/symfony/ cache/CacheItem.php on line 65` * The issue appears to be that you are using an outdated version of this dependency. * Would it be possible for you to either scope your dependencies using Mozart, or update the dependency so that it doesn’t conflict?

I priorize it and come back asap with a fixRegards * Plugin Contributor [Edson Galina Fortes](https://wordpress.org/support/users/glx77/) * (@glx77) * [6 months, 2 weeks ago](https://wordpress.org/support/topic/fatal-error-on-plugins-screen-2/#post-18663822) * I’ve check and i understand the issue. The problem is we want to keep our plugin compatible php. 7.4+ like other plugin (w3tc, yoast, etc) **`psr/cache:^1.0`** → works with PHP **>=5.3, <=7.4**.**`psr/cache:^2.0`** → works with PHP **>=8.0**.**` psr/cache:^3.0`** → works with avec PHP **>=8.**we know php 7.4 is in end of life : [https://www.php.net/supported-versions.php](https://www.php.net/supported-versions.php) but a lot of user still use php 8.0 and lowerI’ll check with my team to scope it on our side and keep you in touch if we do itregards - This reply was modified 6 months, 2 weeks ago by [Edson Galina Fortes](https://wordpress.org/support/users/glx77/). * Thread Starter [alexstandiford](https://wordpress.org/support/users/alexstandiford/) * (@alexstandiford) * [6 months, 2 weeks ago](https://wordpress.org/support/topic/fatal-error-on-plugins-screen-2/#post-18663856) * Thanks Edson! If it helps, using a scoper like Mozart or PHPscoper could give you both the 7.4 compat and also ensure it doesn’t conflict. * I will stand by for an update. * Plugin Contributor [Edson Galina Fortes](https://wordpress.org/support/users/glx77/) * (@glx77) * [6 months, 2 weeks ago](https://wordpress.org/support/topic/fatal-error-on-plugins-screen-2/#post-18663883) * Thanks, [@alexstandiford](https://wordpress.org/support/users/alexstandiford/), yes i’m still using PHPScoper for other project. I just need to check with my team what politic we want to apply. Scope or wait till we upgrade to php 8.0 compat cause in fact php 7.4 (and 8.0) are “dead”. * Plugin Contributor [Edson Galina Fortes](https://wordpress.org/support/users/glx77/) * (@glx77) * [6 months, 1 week ago](https://wordpress.org/support/topic/fatal-error-on-plugins-screen-2/#post-18665427) * Hi [@alexstandiford](https://wordpress.org/support/users/alexstandiford/) , can you try with this plugin : [https://we.tl/t-Guxo5MEVf5](https://we.tl/t-Guxo5MEVf5) i’ve make a build of the plugin for php 8.2+ and it works on my side with dataverse.

Thank you for the speedy reply, I genuinely appreciate it! * This appears to have resolved the problem for us on my end, as well. * Where do we go from here? I could upload this plugin to my production site, but I suspect it needs a bit more testing, and if the next update doesn’t include this upgrade the problem will regress. * Plugin Contributor [Edson Galina Fortes](https://wordpress.org/support/users/glx77/) * (@glx77) * [6 months, 1 week ago](https://wordpress.org/support/topic/fatal-error-on-plugins-screen-2/#post-18665826) * sorry for the disturb, i’ve put here another version of the plugin with the “ real” fix : [https://we.tl/t-GA2WPdtfUT](https://we.tl/t-GA2WPdtfUT)let me explain: The first version i send to you is a build version on php 8.2, it was a quick fix to let you enjoy the plugin haha. I’ve investigate further and find the real issue, the plugin dataverse init the plugin weglot on is admin. I’ve open an issue on my side and had code to prevent weglot load on dataverse admin page and it works.So you can test (and install it on prod if all is ok) cause the fix would be include on the next release.Try the plugin and get me in touchRegards * Thread Starter [alexstandiford](https://wordpress.org/support/users/alexstandiford/) * (@alexstandiford) * [6 months, 1 week ago](https://wordpress.org/support/topic/fatal-error-on-plugins-screen-2/#post-18669941) * He Edson! * Thanks for sending this!

Thanks for your continued effort on this. I appreciate it. These things happen 😊. * I looked at the video and see that you have what’s needed to fix the problem, however when I download the new transfer file I still see the same issue on my site. Maybe the zipped package was the wrong version? * Plugin Contributor [Edson Galina Fortes](https://wordpress.org/support/users/glx77/) * (@glx77) * [6 months ago](https://wordpress.org/support/topic/fatal-error-on-plugins-screen-2/#post-18676455) * Hi [@alexstandiford](https://wordpress.org/support/users/alexstandiford/) , thanks for your patience.
