-
-### I’m using lastpass and stuff is broken
-
-Lastpass arbitrarily breaks tt-rss forms preventing various stuff like saving settings from functioning properly.
-
-### I’m experiencing random failures / UI glitches (error codes 6 & 7) / visibly broken HTML 
-
-Almost every time those are caused by malfunctioning and/or badly written browser extensions. Always try opening tt-rss without browser
-extensions running (i.e. separate Firefox profile, Chrome incognito mode, etc). This way you will be able to figure out which extension
-breaks things.
-
-One of the extensions that causes such problems is Lastpass.
-
-### What should I use - MySQL or PostgreSQL?
-
-PostgreSQL should give you much better performance, especially if you tune it a bit.
-
-### I need a URL I can call to subscribe to feed to integrate with some third party browser extension/application.
-
-<code>SELF\_URL\_PATH/public.php?op=subscribe&feed\_url=%s</code>
-
-SELF\_URL\_PATH = http://your.ttrss.server/tt-rss/
-
-### I need to get the number of unread articles in the simplest way.
-
-<code>SELF\_URL\_PATH/backend.php?op=getUnread&login=LOGIN</code>
-
-No password required. In single user mode, use “admin” for login.
-
-### Feeds stop updating for users who rarely login
-
-See this thread: https://tt-rss.org/oldforum/viewtopic.php?f=1&t=2909&p=23459#p17145
-
-### I have used the update daemon before, but switched away from it. However, the UI keeps nagging me about the daemon not running or not updating feeds or whatever.
-
-Find and delete daemon lock file in <code>LOCK\_DIRECTORY</code>.
-Usually, it’s <code>lock/update\_daemon.lock</code>. You can also remove
-<code>update\_daemon.stamp</code>.
-
-### I have questions about article purging / I don’t think purging works.
-
-In short, you may and will see articles with date older than the cutoff
-for purging. Here’s why:
-
-1. Starred articles are not purged.
-2. Purging is done based on article import date internal to tt-rss which
-could be different from the date specified in the original feed (e.g.
-article has date 01-01-1970, but it was imported today).
-3. When tt-rss sees articles still exist in the feed it bumps the import
-date because otherwise the articles will get purged and reimported
-periodically causing annoyingly reappearing duplicates. This is mostly
-relevant for rarely updated feeds.
-4. Purging is performed when the feed is updated hence disabled updates
-= no purging.

-
-You can see article import date if you mouse over displayed date in
-tt-rss web UI.
-
-Related question:
-
-### I like to manually archive or delete articles and I get duplicates. Why?
-
-Because the articles are still in the feed and get imported again.
-
-### Using Firefox, “OPML Import window” always visible in Preferences
-
-Apparently it’s some addon or a browser setting problem, using clean
-profile helps.
-
-### Tasker client doesn't work
-
-Read this thread: https://tt-rss.org/oldforum/viewtopic.php?f=16&t=3876
-
-### Schema upgrade fails on MySQL 5.7 (and newer)
-
-Error message: <code>Invalid default value for 'last_updated'</code>
-
-See this thread/post for instructions: https://tt-rss.org/oldforum/viewtopic.php?f=1&t=3871&p=22884#p22884
-
-### I have HTTP authentication enabled and get “Your access level is insufficient to run this script” error on login
-
-The problem is that if you have auth\_remote enabled in config.php
-tt-rss tries to automatically log you in as the user specified by the
-server using HTTP authentication, which may not have administrative
-privileges. You will need to either temporarily disable auth\_remote
-(replace it with auth\_internal in config.php), temporarily disable HTTP
-authentication, or give yourself administrative permissions using the
-SQL client:
-
-```sql
-    update ttrss_users set access_level = 10 where login = 'you';
-```
-
-### I’m having performance problems, why is tt-rss so slow?
-
-Most likely you don’t have enough hardware for your requested amount of
-feeds. Switch up to a faster VDS tier or use something else.
