切换到 php7 或者是 php5.6 版本试试, 如果还不行 就是升级失败了!
需要 的话 也可以 联系我QQ 有偿处理的哦

后台清除缓存试试,切换默认模板看下是否报错。 关键现在后台登录不上啊!账号密码都是对的登录没有反应,也不报错

需要的话 可以有偿处理 看是否有参考价值:
这个是什么问题?Cannot use string offset as an array - 问题求助 - Powered by Discuz!
https://www.dismall.com/forum.php?mod=viewthread&tid=17173 如果解决不了,只能有偿排查处理 缓存文件损坏,插件,模板代码不兼容,升级时文件覆盖不完整大概就这些原因。 都查查看 这个错误“Cannot use string offset as an array”(不能将字符串偏移量用作数组),是PHP代码中把字符串变量当成数组来调用导致的,结合Discuz! X3.5的升级场景,核心原因是配置/缓存文件损坏、插件/模板代码不兼容、升级时文件覆盖不完整这三类。
具体原因分析(对应你的报错文件)
从报错的forum_index.php第154行来看,通常是这段代码里调用了某个本应是数组的变量,但实际是字符串(比如缓存数据、配置项被错误赋值为字符串)。常见触发场景:
[*]1. 缓存文件损坏:升级后data/cache/里的缓存文件(比如板块、配置缓存)格式错误,导致读取后是字符串而非数组;
[*]2. 插件/模板代码兼容问题:第三方插件/模板的代码(尤其是旧版本)里,错误地将字符串变量当数组操作(比如$var['key']但$var实际是字符串);
[*]3. 升级文件覆盖不完整:source/module/forum/forum_index.php等核心文件没被正确覆盖,旧代码和新系统的变量类型不匹配。
针对性修复步骤(按顺序操作)
步骤1:清理缓存(最优先)
这是最常见的解决方式:
[*]找到网站目录下的data/cache/文件夹,删除里面所有.php文件(保留index.html,防止目录被访问);
[*]若有data/session/文件夹,也删除里面的所有文件;
[*]刷新首页,看是否恢复。
步骤2:禁用第三方插件/模板
如果清理缓存没用,大概率是插件/模板冲突:
[*]1. 禁用插件:将source/plugin/文件夹重命名为plugin_old(临时禁用所有插件);
[*]2. 切换默认模板:将template/下的非官方模板文件夹(比如自定义模板)重命名,强制使用Discuz!默认模板;
[*]3. 再次刷新首页,若恢复正常,说明是插件/模板的代码不兼容,需要逐个恢复插件/模板排查(升级插件到X3.5适配版,或替换模板)。
步骤3:修复核心文件(覆盖不完整)
如果前两步没用,说明升级时核心文件没覆盖好:
[*]下载Discuz! X3.5的完整安装包,找到source/module/forum/forum_index.php文件;
[*]用新包中的这个文件,直接覆盖网站对应路径的forum_index.php;
[*]同时检查forum.php、index.php是否被完整覆盖(用新包文件替换)。
步骤4:检查配置文件
若以上都没用,可能是config/下的配置文件损坏:
[*]打开config/config_global.php,确认里面的配置项(比如$_config['xxx'])是数组格式(不是被错误写成字符串);
[*]若配置文件混乱,可从备份中恢复config/目录下的文件(升级前的备份),再重新执行升级流程。
收尾建议
修复后,建议先在后台“工具→数据库校验”检查表完整性,再逐步恢复插件/模板(优先升级到X3.5适配版本)。
