Is Slider by Supsystic still maintained?
Not through WordPress.org, and the directory cannot tell you more than that. It closed the Slider by Supsystic listing on 1 March 2024, 2 years and 7 months ago, and gives the reason as "Author Request": the author asked for it to be withdrawn. Some authors do that when a plugin ends and some when they move it to their own site and carry on, so the listing alone does not say which. What is certain is that WordPress can no longer install or update it from the directory.
The evidence
Every figure below is read from the WordPress.org plugin directory. Nothing here is our assessment of the code.
| Directory status | Withdrawn at the author's request, not available from WordPress.org |
|---|---|
| Closed on | 1 March 2024 (2 years and 7 months ago) |
| Reason given | “Author Request” |
| Closure | Stated as permanent in the directory's notice |
| Read from the directory | 12 October 2026 |
Once a listing is closed the directory stops publishing its release date, tested-up-to version, install count and support figures, so the release details below come from the plugin's code archive instead.
What its code archive shows
| Last release | Version 1.8.11 (tagged 21 February 2024) |
|---|---|
| Tested up to | WordPress 6.4 |
| Requires | Not stated |
| Releases in the archive | 13 |

The directory keeps a closed plugin's code readable, and the last release tagged in Slider by Supsystic's archive is version 1.8.11, tagged on 21 February 2024. That is within a month of the listing being closed: it was still being released, and the closure is what stopped the updates. A site still running it has a copy at least 2 years and 7 months old.
That release declared itself tested up to WordPress 6.4, 7 releases behind the current WordPress 7.1.3. The WordPress releases since then have run against code its author has not re-tested, and no fix can reach it through the directory.
The archive holds 13 tagged releases, the oldest still there tagged on 23 June 2020. Its last release described the plugin in one line as: “Responsive Slider by Supsystic - the ultimate slideshow solution. Build image, video and content sliders with professional slider / slideshow templates” That is the job something else has to take over on any site still running it.
Tag dates, almost always the day a release shipped. The count is the tags left, not every release ever made.
What these signals mean
A closed plugin is not a quiet one. A quiet plugin is still listed, and its author could ship a fix tomorrow. A closed one gets no update however long you wait, and the dashboard shows no sign of that: a plugin with no update available looks exactly like one that is up to date.
An author asking for a listing to be closed is not a verdict on the code, and it is not the plugin team acting against the plugin. Authors withdraw plugins when they stop maintaining them, when a product is discontinued, and sometimes when they move distribution somewhere else. The reason alone does not say which of those happened, and the author's own site is the place to find out.
The directory's closure notice says the closure is permanent, so the listing is not expected to return. It has been closed for 2 years and 7 months, so a copy still installed has gone at least that long without an update through WordPress.
What to do about it
Start with the author's own website. A withdrawn listing sometimes means the plugin carries on elsewhere, sold or distributed directly, and sometimes means it has ended. Which of those is true decides whether you are changing where updates come from or replacing the plugin, and only the author can tell you.
Do not start by deleting it. Find out what depends on it, back up the database as well as the files, and test the replacement on a staging copy first, because deleting a plugin can run an uninstall routine that drops its tables.
The directory stops publishing a closed plugin's category, so this page does not suggest alternatives. Any replacement has to do the job that Slider by Supsystic's last release, version 1.8.11, describes above. That release was tested against WordPress 6.4; one worth moving to is tested against 7.1.3 and still listed in the directory.

Questions
Why was Slider by Supsystic removed from the WordPress plugin directory?
The directory gives the reason as "Author Request", quoted as it appears. That means the author asked for the listing to be closed, not that the plugin team acted against it. It does not say why they asked, so the author is the only source for that.
Will Slider by Supsystic keep working if it is already installed?
Usually, for a while. Closing a listing removes the plugin from the directory; it does not reach into sites and switch anything off. What stops is updates, and they stopped on 1 March 2024: WordPress cannot offer an update for a plugin that is not listed, so the installed copy is frozen at whatever version it reached, which can be no later than 1.8.11, the last release in its archive. The dashboard gives no sign of that, because a plugin with no available update looks exactly like one that is up to date.
Could Slider by Supsystic come back to the directory?
Not on the directory's own account: its closure notice says the closure is permanent. If the plugin carries on anywhere, it will be outside WordPress.org, and updates from there do not arrive through the normal dashboard route unless the author supplies their own updater.
Is Slider by Supsystic a security risk?
We do not know, and nothing on this page is a security finding. Vulnerability data for WordPress plugins sits behind paid commercial APIs, and guessing at it from a version number either alarms people about plugins that are fine or implies that everything unflagged has been checked and is safe. Both are worse than saying nothing. What this page reports is maintenance: when the plugin last shipped, which WordPress version its author last tested against, and whether the directory still lists it. Those are facts the directory publishes, and they are what predicts whether a plugin will still work after the next core release.
Read from the WordPress.org plugin directory on 12 October 2026. We report maintenance signals only, and never claim a plugin is insecure. All plugins we cover.
